Product Description
10-32 UNF A2 Stainless Steel Countersunk Socket Screws
These No.10-32 UNF countersunk socket screws are manufactured from A2 stainless steel for good general corrosion resistance. The fine 32 TPI thread is suitable for matching UNF nuts or tapped holes.
The flat countersunk head provides a flush finish when installed in a correctly prepared countersink. The internal hexagon socket accepts a 1/8" Allen key, making these screws suitable for panels, brackets, machinery and general engineering assemblies.

Fitting Information
Use a correctly fitting 1/8" Allen key or hexagon bit with a matching No.10-32 UNF nut or tapped hole. Prepare the countersink to suit the head and select a screw length that provides adequate thread engagement without bottoming out.
Keep the driver fully engaged and tighten steadily. A suitable anti-seize compound can help reduce galling when assembling stainless steel threads. Follow the assembly's tightening requirements and account for lubrication.
