By Head - Nuts & Bolts
Plastic nuts, bolts, screws and washers organised by head type — hex head bolts (DIN 933, M3–M24), cross pan head, cross countersunk, socket head, butterfly screws and wing nuts. Materials include nylon (PA66), polypropylene, acrylic, PEEK, POM, PVC and PTFE in natural, white, black, clear and grey.
How do the head styles differ?
Hex heads take a spanner for high-torque fixing on panels, housings and structural assemblies. Socket heads suit recessed or flush applications where a hex key gives better access. Pan and countersunk heads keep a low profile across covers and sheet fixings. Butterfly screws and wing nuts are hand-tightened — for access panels, jigs and anything needing frequent adjustment without tools.
