Value Collection 701071PR Button Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 701071PR is a button socket cap screw designed for applications requiring a low-profile fastener with high tensile strength. Manufactured from alloy steel with a black oxide coating, this screw measures 3/16 inch in length under the head and is sized at 8-32 UNC thread. It is driven by a 3/32 inch hex socket and is fully threaded along its length. With a hardness rating of 36-43 HRC and thread fit class 3A, it meets ANSI/ASME B18.3 and ASTM F835 standards. This type of fastener is commonly installed by machinists, mechanical assemblers, and maintenance technicians working on equipment, fixtures, and machinery where a flush or recessed fastener head is required.

This button socket cap screw is suited for use in light mechanical assemblies, panel mounting, enclosures, and fixture fabrication where a smooth, dome-shaped head profile is preferred over a standard hex cap or flat-head style. The black oxide finish provides mild corrosion resistance and a non-reflective appearance, making it appropriate for both interior mechanical environments and applications where aesthetics matter alongside function. It is sold individually but requires a minimum order quantity of 100 pieces per order.

Key Features

• Button head profile provides a low-profile, dome-shaped bearing surface for clean finishes on assembled parts
• Alloy steel construction with 36-43 HRC hardness for reliable clamping force in structural and mechanical applications
• Black oxide coating offers mild corrosion resistance and a non-reflective matte finish
• Fully threaded 8-32 UNC right-hand thread with 3A fit class for precise mating and consistent engagement
• Meets ANSI/ASME B18.3 and ASTM F835 standards for dimensional and mechanical conformance
• 3/32 inch hex socket drive compatible with standard ball-end hex keys and hex socket bits

Compatibility

Designed as a standard-specification replacement or stock fastener for any application requiring an 8-32 UNC button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835. Compatible with any mating 8-32 tapped hole with a class 3B thread fit.

Installation Notes

Installation is performed using a 3/32 inch hex key or socket bit driver. Always ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the rated torque range appropriate for 8-32 alloy steel fasteners as specified by your application or engineering standard. Black oxide-coated fasteners are not intended for outdoor or high-humidity environments without additional corrosion protection.
