Product Description

7/8"-9 x 2 1/2" Hex Cap Screws / 18-8 Stainless Steel / Passivated

7/8"-9 x 2 1/2" hex cap screw in 18-8 Stainless Steel, passivated finish. For machinery, structural and general assembly wherever a wrench can reach.

  • HEX HEAD — driven with a socket or wrench, so you can put real torque through it without a bit camming out
  • 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

Frequently Asked Questions

What is the difference between partial thread and full thread?
Partial thread (also called shoulder bolt or tap bolt) has an unthreaded shank for shear strength. Full thread (fully threaded cap screw) provides more clamping engagement. Standard cap screws above 6 inches long are typically partial thread.
How corrosion-resistant is this stainless steel fastener?
Stainless steel fasteners resist rust and corrosion in most environments. For specific corrosion requirements, consult our engineering team or the appropriate ASTM specification.
