Product Description
7/8"-9 x 4 3/4" Hex Cap Screws / Alloy Steel / Grade 8 / Zinc Yellow CR+6
7/8"-9 x 4 3/4" hex cap screw in Medium Carbon Alloy Steel, Grade 8, zinc yellow 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
- YELLOW ZINC — zinc plating with a yellow chromate conversion coat, slightly better protected than clear zinc; interior and sheltered use
- SAE GRADE 8 — medium carbon alloy, quenched and tempered — 150,000 PSI tensile; six radial lines on the head, for suspension, towing and high-clamp joints
- ALLOY STEEL — quenched and tempered for high tensile strength; nearly always supplied with a protective finish since the base metal rusts readily
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.
