Value Collection 307423PR Hex Socket Cap Screw 7/16-20 Unf

Product Description

The VALUE COLLECTION 307423PR is a hex socket cap screw designed for high-strength fastening applications requiring precise torque and a clean, low-profile head. Manufactured from alloy steel with a black oxide finish, this fastener meets ASTM A574 standards for mechanical fasteners. It features a 7/16-20 UNF thread size, a 1-1/4 inch length under head, and a 5/16 inch hex drive. Full threading along the shank provides maximum thread engagement across the grip length. The black oxide coating offers mild corrosion resistance and reduces surface light reflection in precision assemblies.

This cap screw is suited for use in mechanical assemblies, tooling fixtures, machine components, and structural joints where fine-thread fasteners are specified. Fine-thread UNF fasteners are commonly used when vibration resistance, higher tensile loading, or thinner-walled tapped materials are factors in the design. The alloy steel construction handles demanding clamping loads in both industrial and maintenance environments. Licensed mechanics, machinists, and maintenance technicians are the typical installers in shop and field settings.

Key Features

• 7/16-20 UNF fine thread for improved vibration resistance and higher clamp load
• 1-1/4 inch length under head with full threading along the entire shank
• 5/16 inch internal hex drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction meets ASTM A574 mechanical fastener standard
• Black oxide finish provides mild corrosion resistance and low-glare surface

Compatibility

Designed as an OEM-style replacement or direct-fit fastener for applications specifying a 7/16-20 UNF hex socket cap screw meeting ASTM A574 with a 5/16 inch hex drive and 1-1/4 inch length under head.

Installation Notes

Install using a calibrated torque wrench and the correct 5/16 inch hex key or socket bit to avoid rounding the drive recess. Power down or de-energize any equipment before fastener service on live assemblies. Follow applicable ASME or equipment manufacturer torque specifications for the fastener size and grade — do not estimate by feel on structural joints. Inspect threads in the receiving material for damage before installation to ensure full thread engagement.
