Product Description

1 1/2"-6 x 3 1/2" Hex Cap Screws / Grade 5 / Plain

1 1/2"-6 x 3 1/2" hex cap screw in Steel, Grade 5. 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
  • PLAIN — uncoated — oil it, paint it or keep it dry
  • FULL THREAD — threaded to the head, so it grips over the whole length and suits thin or variable stack-ups
  • SAE GRADE 5 — medium carbon, quenched and tempered — 120,000 PSI tensile to 1", 105,000 PSI above; the automotive and machinery default, marked with three radial lines

Frequently Asked Questions

What is the difference between Grade 5 and Grade 8?
Grade 5 (medium carbon steel, 120 ksi tensile strength) is suitable for most industrial applications. Grade 8 (alloy steel, 150 ksi tensile strength) is used for high-strength applications like automotive suspension and machinery. Grade 5 hex heads have 3 radial lines; Grade 8 has 6 radial lines.
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.
