Value Collection 33614 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 33614 is a hex socket cap screw designed for fastening applications requiring a recessed drive and a secure, high-strength connection. It features a 1/4-20 UNC thread and is partially threaded with 4 inches of length under the head. The drive is a 3/16 inch hex socket, compatible with standard Allen keys and hex drivers. Constructed from alloy steel with a black oxide finish, this fastener offers improved corrosion resistance and reduced light glare in service environments. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical and industrial fastening tasks. Installed by machinists, millwrights, and general maintenance technicians.

This socket cap screw is appropriate for machine assembly, equipment mounting, and structural fastening where a flush or low-profile head profile is required. The partial threading allows for precise clamping force across a full grip length, which is common in machinery frames, fixtures, jigs, and mechanical subassemblies. The black oxide alloy steel construction makes it a practical choice where moderate corrosion resistance and strength are both priorities.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 4 inches length under head with partial threading for full grip engagement
• 3/16 inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides moderate corrosion resistance and a non-reflective surface
• Conforms to ASME/ANSI B18.3 socket cap screw dimensional standards

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any application with a corresponding tapped or clearance hole conforming to ASME/ANSI B18.3 specifications.

Installation Notes

Installation should be performed by a qualified technician using a properly sized 3/16 inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Apply appropriate thread lubricant or thread-locking compound as required by the application. Do not exceed the rated torque range for 1/4-20 alloy steel fasteners as specified by the equipment manufacturer.
