Value Collection 701077PR Button Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 701077PR is a fully threaded button socket cap screw designed for applications requiring a low-profile head and a secure hex socket drive. Sized at 8-32 x 7/8 inch, it is manufactured from alloy steel with a black oxide coating that provides moderate corrosion resistance and a dark, finished appearance. The 3/32 inch hex socket drive accepts a standard hex key for installation. This fastener meets ANSI/ASME B18.3 and ASTM F835 standards, confirming dimensional and mechanical conformance. It is suited for general mechanical assemblies, machine components, and panel work where head clearance is limited.

Button socket cap screws are commonly used in fabrication, machine building, industrial equipment, and light structural assemblies where a rounded, low-profile head is preferred over a standard hex cap or flat head. This 8-32 fastener fits applications using unified coarse thread (UNC) in light-gauge metal, plastic housings, or threaded inserts. Machinists, maintenance technicians, and fabricators install this fastener wherever a flush or semi-flush surface finish is needed without sacrificing a solid internal-drive grip. The black oxide finish suits indoor mechanical environments where aesthetics and mild surface protection are both factors.

Key Features

• Fully threaded 8-32 UNC thread form with a right-hand thread direction
• Button head profile reduces overall installed height compared to standard socket cap screws
• 3/32 inch hex socket drive for use with standard hex keys or hex bit drivers
• Alloy steel construction with 36-43 HRC hardness for reliable clamping force
• Black oxide coating for a uniform dark finish and light surface protection
• Conforms to ANSI/ASME B18.3 and ASTM F835 dimensional and performance standards

Compatibility

Designed as a standard UNC replacement or stock fastener for 8-32 threaded holes in mechanical assemblies, enclosures, and machine components requiring a button head profile.

Installation Notes

Install using a 3/32 inch hex key or matching hex bit driver. Ensure the mating threaded hole or insert is clean and free of debris before driving. Do not exceed the rated thread engagement depth for the base material. Always follow applicable assembly torque guidelines for the material being fastened, as over-torquing button head fasteners can strip the shallow head socket.
