Polyimide / Vespel Socket Head Cap Screw Features and Benefits

When it comes to polyimide / Vespel socket head cap screws, it’s all about clearance. These screws are the best choice for applications with limited installation access or clearance. Yet if you have an application with a lot of debris, you may want to select a polyimide / Vespel hex head bolt or hex head cap screw, as they don’t have a socket drive which could get clogged.

Advantages:

  • Ideal for applications with limited access as they require very little clearance around the fastener.
  • Socket heads can be used in locations where externally wrenched fasteners aren't desirable.
  • Weight reduction on application as polyimide / Vespel socket head cap screws are smaller – being that the cylindrical heads of socket screws need less space than hex heads and require no additional wrench space.
  • Also known for safety, reliability and economy.
