Value Collection 88546510 Button Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 88546510 is a button socket cap screw designed for fastening applications where a low-profile head and high shear strength are required. Sized at 8-32 UNC with a 3/8-inch length under head, it features a 3/32-inch hex socket drive and a button-style head with a measured head height of 0.087 inches. The screw is manufactured from alloy steel and carries a Rockwell hardness of 36-43 HRC, making it suitable for moderate-to-high load applications. A black oxide coating provides a uniform dark finish and modest corrosion resistance. Sold in packs of 25, this fastener meets ANSI/ASME B18.3 standards and is used by machinists, assemblers, and maintenance technicians across industrial and mechanical service work.

This button socket cap screw is commonly used in machine assemblies, equipment panels, fixtures, and enclosures where a flush or near-flush fastener head is needed to clear adjacent components or maintain a clean surface profile. The right-hand, Class 3A thread fit delivers a controlled tolerance engagement suitable for precision assemblies. It is compatible with standard 3/32-inch hex keys and L-wrenches. Typical applications include light mechanical assemblies, fabricated brackets, and field repair of industrial equipment.

Key Features

• Alloy steel construction with 36-43 HRC hardness for strength in load-bearing joints
• Black oxide coating for a uniform finish and light corrosion resistance
• Meets ANSI/ASME B18.3 fastener standard
• Sold in a pack of 25 for small-batch use or service kits

Compatibility

Designed as a standard ANSI/ASME B18.3 button socket cap screw with 8-32 UNC threading, compatible with any 3/32-inch hex socket drive tool and suitable for use in threaded holes or with matching nuts conforming to the 8-32 UNC thread standard.

Installation Notes

Installation is performed with a 3/32-inch hex key or ball-end driver. Ensure the mating threaded hole or nut meets the 8-32 UNC standard before driving to avoid cross-threading. Do not exceed the rated hardness or torque capacity of the mating material, particularly when threading into softer substrates such as aluminum or plastic. De-energize or lock out any equipment before replacing or tightening fasteners on live assemblies.
