Fasteners literally hold industry together. They are very important because each component, machinery, vehicle needs a fastener to hold it together. An incorrect or missing fastener can lead to disastrous consequences. A fastener may be a small piece of the design process, but this small component is very significant.
These webpages attempt to give you an insight on numerous options available and a brief guide on their usage. Do browse the various sections. You may also download a number of product datasheets listed out as per the standards.
We have made an attempt to make your understanding of fasteners better and assist you in using them more effectively in your designs.

Plastic is opening up a world of innovations where smaller, lighter and cheaper is driving the markets. But it comes with its own technological challenges such as suitable fastening solutions. The regular screws are completely unsuitable leading to development of specialised screws for use in plastics. An effective solution is to use thread-forming screws with 30°
Black Stainless Steel Screws
Adding to our ever growing range are BLACK 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 colour 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 along with nuts and washers. Other screws can be provided on order.

Captive screws basically are specially designed to lock into position in a hole, enabling easy setting up and removing of the attached pieces even without the complete removal of the screw. This eliminates the possibility of the screw falling down or out of the assembly during maintenance.
Ultra-thin head screw that are up to 77% thinner than conventional screw heads which makes possible flat external surface and contributes low-profile design and weight saving.
No more productivity loss for inserting washers and spring washers into the
No more misplacing washers when screws are removed for maintenance.
No more washers falling into the product while fixing or removing
SEMS Screws are screws pre-assembled 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.
Highly corrosion resistant
High tensile strength.
Lightweight: weighs half of stainless steel.
Non-toxic: safe for the human body
Vibration can cause functional failure of assemblies and joints. One solution is Wedge-Lock Washers. Our range of Heico-lock washers are available in steel, SS-316L and 254-SMO. Suitable for dynamic loads Increases Clamping force Easy installation and removal Secures bolt fastening with preload force.
Keps nut, (also called a k-lock nut or washer nut), is a nut with an attached, free-spinning washer.
