Product Description
3/4"-10 x 3 3/4" Hex Cap Screws / Grade 5 / Zinc
3/4"-10 x 3 3/4" hex cap screw in Steel, Grade 5, zinc 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
- ZINC PLATED — an electroplated barrier for interior and sheltered work; it will not survive sustained weather or contact with treated lumber
- PARTIAL THREAD — an unthreaded shank under the head carries shear on the solid section and lets the joint pull tight rather than jacking apart
- 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
RoHS Compliant
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.
