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 unintrusive aesthetically pleasing finish.

They are available from Fastenright as both Tricle ‘Type A’ and Tricle ‘Type B’ in A2 Stainless Steel.

Available in lengths from 6mm to 30mm, with diameters ranging from M3 to M8.

Non-standard sizes and materials are available to order, including custom parts made to drawings.
