Value Collection 201028P Button Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 201028P is a button socket cap screw designed for applications requiring a low-profile head and high clamping strength. Machined from alloy steel with a black oxide finish, this fastener carries an 8-32 UNC thread and a 3/8-inch length under the head. It is fully threaded and driven with a 3/32-inch hex socket. The black oxide coating provides a degree of corrosion resistance and reduces light reflection, making it suitable for machine assemblies, tooling fixtures, and equipment panels. It meets ANSI/ASME B18.3 and ASTM F835 standards and is rated at 36-43 HRC hardness.

This screw is used in light-to-medium mechanical assemblies where a standard hex cap screw head profile is too tall. Typical applications include machine guards, electrical enclosures, precision equipment housings, and general industrial fabrication. The button head distributes load over a wider bearing surface than a flat-head fastener, making it well suited for softer base materials and sheet metal assemblies. Licensed trades and mechanical contractors will find this size common in panel and cabinet work.

Compatibility

Designed as a standard UNC button socket cap screw for general mechanical and industrial assemblies requiring an 8-32 thread and 3/8-inch grip length with a low-profile hex socket head.

Installation Notes

Install using a 3/32-inch hex key or hex socket driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque range for the 8-32 thread class and material — consult applicable fastener torque tables for alloy steel Class 3A fits. Follow applicable mechanical or electrical code requirements for the assembly type being serviced.
