Value Collection 307425PR Hex Socket Cap Screw 7/16-20 Unf

Product Description

The VALUE COLLECTION 307425PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and industrial equipment. It features a 7/16-20 UNF thread size with a 1-1/2 inch length under head and is fully threaded along its entire length. The 5/16 inch hex drive allows for high-torque installation with a standard Allen key or hex bit driver. Manufactured from alloy steel with a black oxide finish coating, this fastener meets ASTM A574 specifications. It is suited for applications requiring a compact, recessed drive head with strong clamping force. Licensed mechanics, machinists, and maintenance technicians are the primary installers.

This screw is applicable in residential and commercial mechanical environments where a flush or recessed fastener profile is needed. Typical install scenarios include machine frames, brackets, motor mounts, and precision equipment assemblies. The fine 20 TPI thread pitch provides precise clamping adjustment and is well-suited for use in metal-to-metal connections where vibration resistance is a priority. The black oxide coating offers mild corrosion resistance in dry or lightly oiled environments.

Key Features

• 7/16-20 UNF fine thread for precise clamping and vibration resistance
• 1-1/2 inch length under head, fully threaded
• 5/16 inch hex socket drive for Allen key or hex bit installation
• Alloy steel construction meets ASTM A574 standard
• Black oxide finish coating for mild corrosion and wear resistance
• Compact recessed head profile for flush-mount fastening

Compatibility

Designed as an OEM-style replacement or service fastener for mechanical assemblies requiring a 7/16-20 UNF fully threaded hex socket cap screw per ASTM A574 specifications.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 5/16 inch hex key or socket driver. Ensure the mating threaded hole is clean and free of debris before driving. Do not over-drive or cross-thread the fastener, as alloy steel cap screws can fail under improper seating. Follow applicable torque guidelines for the fastener grade and joint material per relevant industry standards.
