Pin Countersunk Head Tricle Bolt

Pin Countersunk Head Tricle Bolts are often found in applications requiring anti-theft or anti-vandalism fasteners.

They can be found in households – in doorknobs, parking poles and more – and also public security, in things such as bus stop timetables, solar panels and vending machines.

Featuring a pin drive and a rounded, three-pronged recess, these fasteners feature a countersunk head which allows them to fit flush into their housing and provide an unobtrusive aesthetically pleasing finish.

Manufactured from A2 Stainless Steel as standard, Pin Countersunk Head Tricle Bolts are available at Fastenright in both Tricle ‘Type A’ and Tricle ‘Type B’ variants, with diameters from M3 to M8 and lengths up to 30mm.

Non-standard sizes, materials and finishes are available to order as specials, including small volume manufacture, modifications and bespoke parts made to drawings. Minimum order quantities apply.
