Value Collection -33649-1 Hex Socket Cap Screw 7/16-14

Product Description

The VALUE COLLECTION -33649-1 is a hex socket cap screw designed for secure mechanical fastening in a wide range of industrial and trade applications. Sized at 7/16-14 UNC with a 1-3/4 inch length under head and fully threaded shank, this fastener delivers consistent clamping force across the full engagement length. It is driven with a 3/8 inch hex key. The alloy steel construction with a black oxide coating provides moderate corrosion resistance and reduces galling during installation. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, confirming dimensional accuracy and mechanical strength requirements for high-stress fastening work.

This cap screw is suited for use in mechanical assemblies, machine frames, equipment mounting, and structural fastening tasks encountered in HVAC, plumbing, electrical, and general mechanical trades. The fully threaded design is appropriate where engagement across the entire shank length is needed. Technicians working on equipment repairs, bracket installations, or component mounting will find this screw a standard-service fastener for medium-duty applications requiring a socket drive interface.

Key Features

• 7/16-14 UNC thread size for reliable engagement in standard tapped holes
• 1-3/4 inch length under head with full threading along the shank
• 3/8 inch hex socket drive for use with standard hex keys or Allen wrenches
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide finish provides moderate corrosion resistance and surface hardness
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 7/16-14 UNC hex socket cap screw suitable for use in any tapped hole or application calling for an ASME/ANSI B18.3 compliant alloy steel socket cap fastener of this thread size and length.

Installation Notes

Install using a properly sized 3/8 inch hex key or socket drive bit; do not use an undersized key as it may round the socket. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before performing fastener work on live mechanical or electrical assemblies. Follow applicable codes and equipment manufacturer torque guidance for the specific joint material and application.
