Adding to our ever growing range are BLACK Passivated Stainless Steel Screws.This finish is very useful to reduce light reflection from parts, provide an integrated finish to black coloured products & parts and also for decorative purposes.

It is a conversion coating that produces a uniform, attractive, and non-reflective black finish on stainless steels. It provides a permanent black color with exceptional strength and elasticity. The finish does not chip, peel, craze, or rub off and provides good resistance to wear and abrasion. The coating reduces friction of moving parts, preventing galling and scoring. Improved corrosion resistance is obtained and there is a negligible dimensional build up, smooth screw assembly is assured.

At present, our shelf stock includes PAN Phillips and CSK Phillips screws in Metric Threads. Other screws can be provided on order.

The Torx compatible drive is a reliable method of fixing screws. This drive can take more torque and does not slip.

The hexalobular socket screw drive, known as Torx or star drive, uses a star-shaped recess in the fastener with six rounded points. It was designed to permit increased torque transfer from the driver to the bit compared to other drive systems. This system features a 15-degree drive angle which provides high torque transfer. Radial forces are drastically reduced resulting in longer tool life. It has vertical sidewalls which increases tool engagement CAMOUT is defined as the force upward on a screwdriver as the torsional force is increased to tighten the screw. Torx Screws do not have camout problems as no camout forces are created to push the driver up and out of the fastener recess. Due to this, the pressure required to keep the screwdriver in the socket reduces significantly and therefore reduces operator muscular stress and fatigue.

Because of these advantages, Torx drive screws are very popular in the automotive and electronics industries.

Our range of TX PAN head screws is presently in Stainless Steel.

SEMS Screws are screws preassembled with free spinning washers. The assembly typically contains one plain washer and one split spring washer. The washers are held in place with the major diameter of the thread being larger than the hole of the washer. This is achieved by inserting the washers before thread rolling.
Advantages
- Increased productivity by eliminating hand assembly of washers with the screws.
- Permanent assembly ensuring that the washers are not misplaced.
- Safety for the product as there is no chance of a washer being dropped into the assembly.

The unique “trilobular” shape of the Taptite screw roll forms a mating thread in an unthreaded pilot hole. The threads are work hardened as they are formed, providing a strong joint or assembly. By elastic recovery, the metal fills in behind the triangular lobes to provide maximum contact and a secure assembly. The tri-lobular shape of the screw shank reduces friction during driving to assure low driving torque, generates a prevailing torque that exceeds the level of locking screw; an interference fit provides resistance to vibrational loosening.

These screws not only save money by eliminating the step of tapping, but they also avoid cross threading issues, lower scrapped costs, increase assembly time and reduce high tooling costs.

The Countersunk Head profile enables flush fixing.
Our range is as per DIN 7500 in Stainless Steel
