Product Description

1/4"-20 x 2 1/2" Machine Screws / Unslotted / Hex Washer Head / 18-8 Stainless Steel / Passivated

1/4"-20 x 2 1/2" machine screw in 18-8 Stainless Steel, passivated finish. For threading into a tapped hole or a nut in assemblies and enclosures.

  • HEX WASHER HEAD — an integral flange under a hex head spreads load without a separate washer and stops pull-through in sheet material
  • HEX DRIVE — wrench or socket driven — the highest practical torque and no bit to cam out
  • PASSIVATED — an acid treatment that strips free iron from the stainless surface so it cannot bleed rust down the workpiece
  • FULL THREAD — threaded to the head, so it grips over the whole length and suits thin or variable stack-ups
  • 18-8 STAINLESS — the 300-series austenitic workhorse — non-magnetic, excellent general corrosion resistance, and it will not rust-stain the surface around it
