We stock over 21 Allen cap (socket cap) screws
Allen cap screws need an allen key to do them up. They are ideal as a nice looking alternative to hex set or pan head screws, for example on a crankcase side or a flywheel cowling. Also they may deter the casual thief as any screw can be undone with a screwdriver or adjustable spanner whereas not everyone carries allen keys around. The length refers to the length of the threaded section only. The other size is the thread size NOT the size of the allen key for adjusting it. As a guide the following information may be helpful. A 5mm allen cap screw needs a 4mm allen key. A 6mm allen cap screw needs a 5mm allen key. A 7mm allen cap screw needs a 5mm allen key. An 8mm allen cap screw needs a 6mm allen key. A 10mm allen cap screw needs an 8mm allen key. A 6mm countersunk socket screw needs a 4mm allen key. |
