3/4-10 x 3.25 in Socket Head Cap Screws

These Grade 8 alloy steel fasteners feature a black oxide finish and a 5/8 in socket drive. The pack contains 25 pieces with a 3.25 in overall length and 2 in minimum thread length. They conform to ANSI B 18.3 dimensional standards.

Builders needing high-strength inch fasteners

Mechanics and fabricators assembling heavy equipment or structural joints will find the Grade 8 rating and socket head profile suitable for high-torque applications. Buyers requiring fully threaded shanks, metric threads, or corrosion-resistant stainless steel should consider other fastener types.

Verify thread compatibility and tool fit

Confirm the 3/4-10 thread matches the tapped hole or nut specification in your assembly. Ensure a 5/8 in hex key or bit is available for the socket drive. Check that the 1.125 in head diameter and 0.75 in head height clear adjacent components.

Questions about this item

What size hex key fits the 5/8 in drive socket on these 3/4-10 cap screws?

A 5/8 in hex key or socket fits the drive on each 3/4-10 x 3.25 in alloy steel cap screw in the 25-piece pack.

Will these Grade 8 alloy steel screws match the strength of older Grade 5 hardware I keep?

Grade 8 alloy steel exceeds Grade 5 tensile strength, so the 3/4-10 x 3.25 in screws are stronger than the older Grade 5 hardware you may retain.

How can I confirm the 3.25 in length and 1.125 in head diameter after installation?

Measure from under the head to the tip for 3.25 in overall length and across the head flats for 1.125 in diameter to verify the ANSI B 18.3 dimensions.
