Collated screw system ... a new dimension in screw driving.
Tools specialist unveils new range
01 December 2007
Hilti Corporation showcased innovative and useful tools that its scientists and technical experts have developed in recent months at an Innovation Day event at the company’s headquarters in Liechtenstein.
Company officials gave a live demonstration of the tools, highlighting their cutting-edge technology, properties and applications. These included the SD 5000 drywall screwdriver with the SMD 57 screw magazine, the GX 120 direct fastening system, HIT-HY 70 injectable adhesive fastening system, X-BT fastening system, the CP 660 firestop foam and the PS 200 rebar locator.
SD 5000 and SMD57
Among the latest products highlighted was the collated screw system comprising of the SD 5000 drywall screwdriver with the SMD 57 screw magazine that product manager Jose Cavadas described as “taking screw driving performance to a new dimension”.
Hilti SD 5000 screwdriver, SMD 57 magazine and collated screws have been developed together, tested together and perfectly matched to each other to ensure that customers benefit in full from the Hilti Power Effect – a superior system performance that adds up to much more than just the sum of its components, he said.
Offered in packs of 50, the new collated drywall screw system is twice as fast as single screws. Given that labour costs are rising and skilled labour is hard to get, Hilti provides once more a solution were interior finishing professionals boost their efficiency, he added.
The SD 5000 drywall screwdriver has a rated power of 710 W, a maximum torque of 9.5 Nm, a maximum no-load running speed of 0 to 5,000 rpm and a weight of 1.4 kg. High torque is provided for wood application with the SD 2500 which comes with a maximum torque of 19 Nm and a no-load running speed of 0 to 2,500 rpm.
Applications of the new system relate to fastening drywall panels on wall and ceilings and assembling and fastening drywall tracks for framing as well as driving screws into wood.
Even cordless overhead work is facilitated with the premium tool SF 4000-A and the SME magazine extension. The system also eliminates the need for a ladder, scaffolding or a power supply to fasten drywalls panels on the ceiling.
GX 120
Hilti – which has been offering a direct fastening system that using gas as power source since 2003 – has launched the second-generation GX 120, a tool that professionals in the construction industry have been waiting for, said a Hilti spokesman.
As a pioneer, Hilti has more than 50 years of experience working with professionals in direct fastening tools.
The GX 120 features an electronically-controlled gas injection and the world’s first gas level indicator, he said. There is no battery to charge that means no waste of productivity. The tool is considered ideal for a wide range of fastening jobs on concrete, masonry, sand-lime stone or steel and boosts efficiency – in non-stop fastening applications, 750 nails can be driven with a single gas can.
The GX 120 employs the proven piston principle which makes dangerous through-shots virtually impossible, he adds.
Purchasers of a Hilti gas tool are offered thorough training in its operation and simple job site maintenance for all users. Hilti provides for each one a pocket-sized user certificate to assure health and safety on each job site in the Gulf.
Furthermore, Hilti provides detailed application documentation, special design software and a Direct Fastening Technology Manual produced in conjunction with an international science and technology institute.
HIT-HY 70
“The new Hilti HIT-HY 70 injectable adhesive fastening system, consisting of only a few individual parts, ensures superior holding power in a huge range of applications”, said Fabian Neidhart, product manager for chemical anchors worldwide.
The system is the new generation coming after Hilti’s renowned HIT-HY 20 and HIT-HY 50 injectable adhesive mortars, which have been used with great success throughout the world.
With this new system, only two connectable composite sleeve sections are required to cover up to five different anchorage depths. Its unique adhesive filling level indicator makes it easy for the user to determine when the right quantity of adhesive has been injected, for a perfect fastening.
“HY” stands for “hybrid” – a special hybrid mortar featuring an organic and inorganic curing mechanism.
Thanks to its easily adjustable anchorage depth, HIT-HY 70 covers a wide range of load values and meets the demanding requirements of high fire ratings.
With Hilti HIT-HY, fastening components of virtually all kinds can be installed, in applications requiring internal or external threads and including rebar for masonry wall reinforcement.
X-BT
The Hilti X-BT is described as an innovative way of fastening to pre-painted steel without damaging the protective coating. It is designed to work on construction steels as thin as 8 mm (5/16”) in environments where corrosion is an issue, such as offshore, shipbuilding and petrochemical industries.
Hilti spokesman Jean-Louis Milhes said: “X-BT studs reduce costs by doing away with rework to pre-painted steel base materials. It boosting productivity by up to 95 per cent in comparison with conventional techniques such as welding.”
Based on Hilti’s DX direct fastening principle, X-BT is made of A4/AISI 316 high-grade stainless steel for long life and has a durable sealing washer. The special flat tip is designed to avoid through-penetration of the base material. During the driving process, the washer forms a permanent seal around the entry point.
X-BT is the alternative to such methods as stud welding, through-bolting and clamping. It also serves as an alternative to the standard Hilti DX technique where through-penetration is not desired.
X-BT supports a wide range of applications such as fasten gratings, cable connectors (T-bars), lighting, cable trays, junction boxes, instrumentations and pipe hangers, among others. The X-BT system is easy and safe to use; a single user can set more than 100 studs in an hour and no rework is involved.
CP 660 firestop foam
Termed a world’s first in firestopping, the Hilti CP 660 is a single-system solution for firestopping and smokesealing. This universal firestop foam is supplied in foil packs that allow quick, easy application using Hilti HIT system dispensers. Marcel Ae, market development manager, said: “CP 660 is presented as the new standard for the installation of firestop seals in all small to medium-sized cable and pipe penetrations.”
This two-component foam comes in handy foil packs for virtually drip-free, easy, well-controlled application using the well-proven, ergonomically-designed Hilti HIT system dispensers.
The system adopts a three-phase technology, moving from application of the foam, its expansion within a minute and curing (complete hardening takes about 10 minutes). During this time, the foam can be pressed into shape in the opening.
Another practical advantage is that additional single cables can be installed at a later date simply by pushing them through the foam. No cutting or subsequent filling is required.
PS 200
Hilti’s Business Unit Measuring Systems came up with a high-tech solution for rebar detection, bar diameter estimation and concrete coverage analysis.
Julia Zanona, product manager for detection said that the upgraded PS 200 Ferroscan is the ideal tool where rebar configuration and location is critical. The Hilti PS 200 is a quick and portable system for detecting the position and diameter of reinforcement in concrete and measuring depth of cover. Using the portable scanner, information is gathered from below the concrete surface. The ratio of rebar spacing to depth of coverage must be greater than 2:1. The PS 200 can estimate rebar diameter at depths up to maximum 60 mm with a +/-1 mm standard diameter accuracy.
The customer can immediately have a viewing of the image on the job site by using an infra-red connection with the PS 200 portable monitor. When more detailed evaluation is needed, the PSA 90 PC software helps the user prepare an in-depth analysis and print-ready reports include a voice recording to a scan.
The “Quickscan” mode for continuous scan on stretches of concrete up to 30 m is particularly useful in tunnel and bridge applications where a minimum cover over rebar is critical, or where quality control or documentation of precast structural elements is required.
Hilti’s local field engineer can provide customers with further advice, based on practical experience, for finding a secure drilling point for drilling or coring work, carrying out structural analysis quickly and exactly in a non-destructive manner and determining coverage over the entire surface of a structure.
