Fasteners are often misnamed. Asking for the wrong thing will result in disappointment or, in some shops, ridicule.

• A setscrew is threaded all the way to the end and usually has a hexagonal head. It is often wrongly called a bolt.
• A bolt has a smooth portion as well as a threaded portion
• Pozidrive and Philips are both known as cross-head screws and use a '+' shaped screwdriver tip
• Pozidrive are more common and have short radial lines between the main grooves
• A single slot right across the head for use with a common flat-blade screwdriver is called a slotted head
• A full rounded screw top is called a round head
• A shallow round head is called a pan head
• A cylindrical head with an allen / hex key hole is called a cap head screw, cap screw or socket head screw
• A conical head intended to lie flush with the surface is called a countersunk head

How

If you are a member, these may be used for your personal project. Please be excellent and respect other members : if you use more than a few, make a donation to help pay for your usage and email the keeper to ensure supplies are replaced.

Pleas keep the drawers tidy. If you drop them, put them back correctly. If you take more than you need, return the excess to the correct drawer.

We can't hold every possible size but the initial stock is just to get things started. It may be possible to stock additional items. If you think there is a need to extend the range please note it here or in email. Be sensible or you'll be ignored.

Specialist - these should perhaps be bought personally rather than as general stock, but are noted here to help gauge interest. Long metric screws are not exotic but if they're very long compared with thickness they tend to be expensive .. e.g. 10 x the cost of a short screw. And it's often the case that a thicker screw is appropriate for longer lengths.
