Value Collection -33684-1 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION -33684-1 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. It features a 5/8-11 UNC thread size and measures 2-1/4 inches in length under the head with full threading along the entire shank. The screw is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. A 1/2-inch hex drive socket is required for installation. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding structural and mechanical joint applications.

This socket cap screw is used in a wide range of industrial and mechanical assembly scenarios where a recessed, low-profile fastener head is required. Typical applications include machinery frames, jigs, fixtures, tooling plates, hydraulic components, and structural assemblies. The fully threaded shank allows for maximum thread engagement across the full grip length, which is particularly useful in thinner material stacks or when threading directly into tapped holes without a nut.

Key Features

• 5/8-11 UNC thread size for standard unified coarse thread engagement
• 2-1/4-inch length under head, fully threaded shank
• Alloy steel construction meets ASTM A574 for high tensile strength
• Black oxide finish for moderate corrosion resistance and surface hardness retention
• 1/2-inch hex socket drive for torque transfer with standard socket tooling
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any tapped or through-hole application accepting a 5/8-11 UNC thread fastener.

Installation Notes

Installation requires a 1/2-inch hex socket driver or Allen key of appropriate length and quality for the torque demands of alloy steel cap screws. Ensure the mating tapped hole or nut is clean and free of debris before threading. Follow applicable torque specifications from your engineering reference or relevant ASME standards for 5/8-11 UNC alloy steel fasteners. Do not mix with metric or non-UNC hardware in the same joint.
