Value Collection 701191PR Button Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 701191PR is a button socket cap screw designed for applications requiring a low-profile head with high-strength clamping force. Manufactured from alloy steel with a black oxide coating, this fastener meets ANSI/ASME B18.3 and ASTM F835 standards. The 3/8-24 UNF thread provides fine-pitch engagement suitable for precision assemblies, and the 7/32-inch hex socket drive accepts standard hex keys. With a hardness rating of 36-43 HRC, this screw is suited for demanding mechanical and structural applications where a flush or semi-flush head profile is required. Licensed tradespeople and industrial maintenance technicians commonly install this fastener in equipment assemblies and machinery.

This button socket cap screw is used in machinery, fixtures, tooling, and mechanical assemblies where clearance above the fastener head is limited. The fully threaded shank and fine-thread UNF specification make it well-suited for close-tolerance applications in metal-to-metal joints. The black oxide finish provides mild corrosion resistance and reduces surface reflectivity, making it a common choice in precision mechanical environments. This fastener is sold individually, with a minimum order quantity of 10 units.

Key Features

• Alloy steel construction with 36-43 HRC hardness for high-strength fastening
• Black oxide coating for mild corrosion resistance and low-reflectivity finish
• 3/8-24 UNF fine-thread specification for precise thread engagement
• 7/32-inch hex socket drive compatible with standard hex keys
• Fully threaded shank for maximum thread engagement along the full length
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-fitment fastener for mechanical assemblies requiring a 3/8-24 UNF button socket cap screw with a 2-1/2-inch length under head and 7/32-inch hex drive.

Installation Notes

Installation is performed using a 7/32-inch hex key or socket bit driver. Ensure mating threads are clean and free of debris before installation. Apply appropriate thread lubricant or threadlocker per the equipment manufacturer's specifications. Always torque fasteners per the assembly drawing or applicable engineering standard — do not overtighten, as this may exceed the clamp load limits of the joint material.
