Value Collection 701182PR Button Socket Cap Screw 3/8-16x4

Product Description

The VALUE COLLECTION 701182PR is a button socket cap screw designed for mechanical assemblies where a low-profile head is required and torque is applied via an internal hex drive. Sized at 3/8-16 with a 4-inch length under the head, this fastener is fully threaded and manufactured from alloy steel with a black oxide finish. Hardness is rated at 36-43 HRC, making it suitable for high-strength structural and mechanical applications. The 7/32-inch hex socket drive is used with a standard hex key or Allen driver. It conforms to ANSI/ASME B18.3 and ASTM F835 standards.

This button socket cap screw is used in industrial, manufacturing, and mechanical maintenance applications where a flush or recessed fastener profile reduces snagging or interference with adjacent components. The black oxide coating provides mild corrosion resistance and reduces light reflection, which is beneficial in tooling, machinery, and equipment enclosure assemblies. Right-hand thread direction and UNC thread standard make this compatible with standard unified coarse-threaded hardware. Thread fit is Class 3A for close tolerance engagement.

Key Features

• Button head profile provides low-profile clearance in confined or tight assemblies
• Alloy steel construction with 36-43 HRC hardness for high-strength applications
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Fully threaded 3/8-16 UNC, Class 3A fit for precise thread engagement
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards
• 7/32-inch internal hex socket drive compatible with standard hex keys

Compatibility

Designed as an OEM-style replacement or standard-specification fastener for mechanical assemblies requiring a 3/8-16 UNC button socket cap screw per ANSI/ASME B18.3 and ASTM F835.

Installation Notes

Installation should be performed by a qualified mechanic or maintenance technician using a properly sized 7/32-inch hex key or socket driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque capacity of the button head drive interface, as button heads have a lower drive engagement depth than standard socket cap screws. Always verify thread engagement depth and hardware compatibility before final torquing.
