Most popular for use on bodywork and plastics, these attractive dome heads are manufactured with the smallest possible Allen key drive, whilst the large head diameter spreads the load and gives the most appealing cosmetic appearance. Though these are not just about looks. Made from 316 Stainless Steel and machined with rolled threads, these bolt are strong, highly polished and corrosion resistant. Sold here individually but also available in packs of 5 & 10.
Prefer something a little more subtle? Stainless Steel is also available in black, which not only looks great but has other benefits too..
This beautiful long lasting black finish results from an application of Diamond Like Carbon Coating (DLC) This gives supreme hardness and corrosion resistance provided by a nano composite coating, which increases the fastener lifetime dramatically and helps to prevent galling. By incorporating them right from the beginning, the overall system cost can be held level or may even be reduced.
Please note that due to this special coating Black Stainless Steel is not identical to our Black Aluminium.

Manufactured from A316 stainless steel. A316 stainless steel has a minimum chromium content of 16.5% and contains elements of carbon, molybdenum, silicon, phosphorus, sulphur, nickel, manganese and iron, all of which add properties of formability, strength, weldability and enhanced corrosion resistance. All of the fasteners are highly polished to a mirror-like finish.
