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 6AL-4V (Grade 5) Titanium and machined with rolled threads, this bolt is strong, lightweight and highly corrosion resistant.
The beautiful, long lasting black finish results from an application of Diamond Like Coating (DLC) this gives supreme hardness and corrosion resistance provided by a nano composite coating. This coating increases the fastener lifetime and helps to prevent galling.
DLC coatings increase the component lifetime dramatically. By incorporating them right from the beginning, the overall system cost can be held level or may even be reduced.
Also available in Blue, Gold and Purple Haze anodised Titanium. Please note that our coloured Titanium is not identical to our Aluminium range.

Made from aircraft grade titanium 6AL-4V (grade 5), the outstanding benefits are that we roll the threads to produce greater fatigue strength and reduce galling. These bolts are in excess of 120,000psi ultimate tensile strength, suitable to replace both Grade 5 and Grade 8 steel bolts. We offer Race Spec drilled Flanged Hex Head Bolts, Flanged Hex Head, Tapered Socket Cap, Countersunk Bolts, Dome Head Bolts, Nuts and Washers – from 3mm to 12mm.
