Value Collection -33711-2 Hex Socket Cap Screw 1-8 Unc

Product Description

The VALUE COLLECTION -33711-2 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and trade assembly work. Threaded to the 1-8 UNC standard, this screw measures 2.25 inches in length under the head and is fully threaded along its entire shank. The 0.75-inch hex drive socket interface requires a standard hex key or Allen driver for installation. Constructed from alloy steel with a black oxide finish coating, this fastener offers a combination of tensile strength and basic corrosion resistance suitable for interior and controlled-environment applications. This screw meets ASME/ANSI B18.3 and ASTM A574 standards.

This cap screw is suited for mechanical assemblies, machinery mounting, jig and fixture construction, and general structural fastening where a recessed drive is preferred over an external hex head. The fully threaded shank provides maximum thread engagement across the full fastener length, making it appropriate for through-bolting or threading directly into tapped holes in metal components. Minimum order quantity is 10 pieces.

Key Features

• 1-8 UNC thread size for standard coarse-thread engagement in steel and ferrous materials
• Fully threaded shank for maximum thread engagement along the entire length
• 0.75-inch hex socket drive compatible with standard hex keys and Allen drivers
• Alloy steel construction meets ASTM A574 requirements for socket head cap screws
• Black oxide finish provides basic corrosion resistance and a low-reflectance appearance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 1-8 UNC hex socket cap screw for use in any application requiring an ASME/ANSI B18.3-compliant alloy steel socket head fastener in a coarse-thread tapped hole or with a compatible nut.

Installation Notes

Installation should be performed by a qualified mechanic or tradesperson using a properly sized 0.75-inch hex key or socket driver. Always verify that the receiving tapped hole or nut matches the 1-8 UNC thread specification before installation. Apply appropriate thread-locking compound or torque to specification per the equipment manufacturer's guidelines. Black oxide finish is not a substitute for plated or coated fasteners in wet or high-humidity environments.
