1/4-20 x 1/8 Knurled Point 18-8 Stainless Steel Socket Set Screw is used when a blind tapped hole or collar needs the bite of a serrated cup point in 18-8 stainless.

Instead of presenting a smooth cup edge, the knurled point creates small teeth at the contact ring so the fastener can resist vibration-driven movement in the right mating material.

For stainless assemblies, review thread fit and installation practice because stainless-on-stainless contact can raise galling concerns if the joint is assembled dry or repeatedly adjusted.

Use cases for 1/4-20 x 1/8 include replacement assemblies, maintenance repairs, and exact-size service work and machine rebuilds, process-area equipment, and small retained components where a headless internal-hex screw keeps the component exterior clear.

For 1/4-20, UNC has 20 threads per inch; check the 1/8 in. length against tapped depth and point location. Check the screw length against the contact location so the point reaches the intended surface without bottoming out. Cold Headers can assist with exact-size stainless set screw sourcing for maintenance, distributor, and production needs.
