Value Collection 701183PR Button Socket Cap Screw 3/8-24

Product Description

The VALUE COLLECTION 701183PR is a button socket cap screw designed for applications requiring a low-profile head with high clamping strength. It features a 3/8-24 UNF thread and measures 7/8 inch under the head, making it well-suited for precision assemblies where fastener height clearance is limited. The alloy steel construction paired with a black oxide finish provides corrosion resistance and a clean, non-reflective appearance. Drive engagement is achieved through a 7/32 inch hex socket, compatible with standard Allen keys and hex bit drivers. This fastener meets ANSI/ASME B18.3 and ASTM F835 standards, making it a go-to choice for machinists, millwrights, and mechanical contractors working to industry specifications.

This screw is appropriate for use in machinery, fixtures, jigs, and structural assemblies where a flush or near-flush fastener head is required. The fully threaded shank and right-hand thread direction suit a wide range of tapped hole applications. It is commonly installed in metal fabrication shops, production environments, and maintenance settings. Hardness is rated at 36-43 HRC, supporting high-load and vibration-prone assemblies. This fastener is sold individually but requires a minimum order quantity of 100 units.

Key Features

• 3/8-24 UNF fully threaded, right-hand thread with 3A thread fit class for precise engagement
• Low-profile button head at 0.199 inch head height for clearance-critical installations
• 7/32 inch hex socket drive compatible with standard Allen keys and hex bit drivers
• Alloy steel construction with 36-43 HRC hardness for high-load and vibration-prone applications
• Black oxide finish for corrosion resistance and reduced surface reflectivity
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard-dimension replacement or new-installation fastener for any application requiring a 3/8-24 UNF button socket cap screw per ANSI/ASME B18.3 and ASTM F835 specifications.

Installation Notes

Installation is performed by machinists, millwrights, or mechanical maintenance technicians using a 7/32 inch hex key or socket bit driver. Ensure the mating tapped hole is clean and dimensionally correct for a 3/8-24 UNF 3A thread fit before installation. Follow applicable torque guidelines from ASME or fastener manufacturer documentation for the application load and material. Do not substitute a metric hex key, as improper drive fit can round the socket and damage the fastener head.
