Value Collection 011343PR Hex Socket Cap Screw 7/16-20 Unf

Product Description

The VALUE COLLECTION 011343PR is a partially threaded hex socket cap screw designed for high-strength fastening in precision mechanical assemblies. It features a 7/16-20 UNF thread and measures 2 inches under the head. The screw is machined from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. A 3/8-inch hex drive socket is required for installation. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where load-rated socket head cap screws are specified.

This screw is suited for use in equipment assembly, fixture fabrication, tooling, and machinery maintenance across industrial, commercial, and trade environments. The 7/16-20 UNF fine thread provides greater thread engagement per inch than coarse thread equivalents, which is advantageous in metal-to-metal joints where vibration resistance or precise clamping force is required. Machinists, millwrights, and maintenance technicians commonly install this fastener type in steel and aluminum components.

Key Features

• 7/16-20 UNF partially threaded shank provides fine-thread engagement for vibration-resistant joints
• 2-inch length under head suits medium-depth through-hole and tapped-hole applications
• Alloy steel construction meets ASTM A574 high-strength socket head cap screw specification
• Black oxide finish offers mild corrosion protection and a low-reflectance surface
• 3/8-inch hex drive socket engagement compatible with standard hex key and socket driver tooling
• Conforms to ASME/ANSI B18.3 dimensional standard for socket head cap screws

Compatibility

Designed as an OEM-style replacement or maintenance fastener for machinery, fixtures, and assemblies specifying a 7/16-20 UNF partially threaded alloy steel socket head cap screw per ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation requires a 3/8-inch hex key or socket driver; always confirm the drive tool is fully seated before applying torque to avoid rounding the socket. De-energize and lock out all equipment before replacing fasteners in live assemblies per applicable OSHA lockout/tagout procedures. Inspect mating threads for damage or contamination before installation. Do not substitute a coarse-thread fastener in a fine-thread tapped hole.
