Value Collection 701181PR Button Socket Cap Screw 3/8-16x3

Product Description

The VALUE COLLECTION 701181PR is a button socket cap screw designed for fastening applications that require a low-profile head and high-strength clamping force. The screw features a 3/8-16 UNC thread and measures 3 inches under the head, with full threading along the shank. Drive engagement is through a 7/32 inch hex socket. Built from alloy steel with a black oxide finish, this fastener delivers hardness in the 36-43 HRC range and meets ANSI/ASME B18.3 and ASTM F835 standards. It is installed by machinists, maintenance technicians, and fabricators working with metal assemblies where a flush or recessed head profile is required.

This button socket cap screw is suited for use in machinery, fixtures, and structural assemblies where clearance above the fastener surface is limited. The button head style distributes clamping load over a wider bearing area compared to a standard socket head cap screw, making it a practical choice for soft-material clamping faces or panels. The black oxide coating provides mild corrosion resistance and reduces light reflection in precision environments. Applications include general industrial equipment, tooling plates, enclosures, and mechanical assemblies across manufacturing and maintenance trades.

Key Features

• 3/8-16 UNC right-hand thread with Class 3A thread fit for precise engagement
• Full thread length of 3 inches under head for maximum grip in through-hole applications
• 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 tensile strength
• Black oxide finish for mild corrosion resistance and low-reflectance appearance
• Meets ANSI/ASME B18.3 and ASTM F835 dimensional and mechanical standards

Compatibility

Designed as an OEM-style and aftermarket replacement button socket cap screw for 3/8-16 UNC threaded holes requiring a low-profile button head and 7/32 inch hex socket drive.

Installation Notes

Installation is performed using a 7/32 inch hex key or Allen-type driver. Ensure the mating threaded hole or nut is clean and free of debris before driving. Power down and de-energize any equipment before accessing fastener locations on live machinery. Do not exceed the mechanical limits of the fastener by applying impact tools at full torque without appropriate torque management.
