Product Description
1/4"-28 x 1" Security Machine Screws / Spanner Drive / Pan Head / 18-8 Stainless Steel / Passivated
1/4"-28 x 1" security screw in 18-8 Stainless Steel, passivated finish.
- PAN HEAD — a rounded head with a wide bearing face — the general-purpose choice where flush seating is not required
- PASSIVATED — an acid treatment that strips free iron from the stainless surface so it cannot bleed rust down the workpiece
- 18-8 STAINLESS — the 300-series austenitic workhorse — non-magnetic, excellent general corrosion resistance, and it will not rust-stain the surface around it
- STAINLESS STEEL — corrosion resistant through the whole section, not just the surface — a scratch does not start a rust bloom
- COARSE THREAD (UNC) — the default inch thread — faster to run down, more tolerant of dirt, damage and plating build-up
