Value Collection 307429PR Hex Socket Cap Screw 7/16-20 Unf

Product Description

The VALUE COLLECTION 307429PR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling fixtures, and equipment fabrication. It features a 7/16-20 UNF thread size with a 1-3/4 inch length under head and is fully threaded for maximum thread engagement. The screw is driven with a 5/16 inch hex key. Constructed from alloy steel with a black oxide finish coating, it meets ASTM A574 standards, making it suitable for demanding load-bearing and torque-critical connections. Machinists, millwrights, and maintenance technicians use this fastener where a low-profile socket head and precise thread pitch are required.

This screw is used in light industrial and commercial applications where UNF fine-thread engagement is needed for close-tolerance assemblies. Typical install scenarios include machine frames, jigs, dies, hydraulic components, and precision equipment where vibration resistance and controlled clamp load are priorities. The fine 20 TPI thread pitch provides better holding strength in thinner materials compared to coarse-thread equivalents. Sold in minimum order quantities of 5 pieces.

Key Features

• 7/16-20 UNF fine thread for precise engagement and vibration resistance
• Fully threaded shank for maximum thread engagement across the full length
• Alloy steel construction meets ASTM A574 standard for high-strength socket cap screws
• Black oxide finish coating provides mild corrosion resistance and reduced light reflection
• 5/16 inch hex drive accepts standard hex keys and Allen bit drivers
• Low-profile socket cap head suits recessed and flush-mount fastening applications

Compatibility

Designed as an OEM-style replacement or standard-service fastener for any assembly requiring a 7/16-20 UNF fully threaded hex socket cap screw conforming to ASTM A574.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 5/16 inch hex key or Allen bit driver. Ensure mating threads are clean and free of debris before installation. De-energize and lock out any equipment before replacing or installing fasteners in operational machinery. Do not substitute a coarse-thread fastener in a fine-thread tapped hole.
