Value Collection 88546478 Button Socket Cap Screw 10-24

Product Description

The VALUE COLLECTION 88546478 is a button head socket cap screw designed for mechanical assemblies where a low-profile fastener head is required. The button head sits flush and wide, distributing clamping load across a broader surface area than a standard socket cap head. Sized at 10-24 UNC with a 1/2 inch length under the head, it accepts a 1/8 inch hex socket drive. The screw is manufactured from alloy steel and finished with black oxide coating, which provides mild corrosion resistance and a matte appearance. Hardness is rated at 36-43 HRC. Each package contains 25 pieces.

This screw is used in general mechanical fabrication, machine assembly, and maintenance applications where a clean, low-profile fastened joint is needed. The 10-24 UNC thread is a common size across industrial equipment, panels, enclosures, and light structural assemblies. The black oxide finish makes it a practical choice in applications where appearance matters alongside basic corrosion protection. It conforms to ANSI/ASME B18.3 fastener standards, making it interchangeable with other compliant hardware of the same size. Machinists, fabricators, and maintenance technicians routinely install this type of fastener across a wide range of trade and industrial settings.

Key Features

• 10-24 UNC right-hand thread for broad compatibility with standard tapped holes
• Button head profile provides low clearance and wide load distribution
• 1/8 inch hex socket drive for use with standard hex keys or socket drivers
• Alloy steel construction with 36-43 HRC hardness rating
• Black oxide coating for mild corrosion resistance and reduced light reflection
• Conforms to ANSI/ASME B18.3 fastener standard

Compatibility

Designed as a standard-compliance replacement or stock fastener for any application requiring a 10-24 UNC button socket cap screw per ANSI/ASME B18.3 specifications.

Installation Notes

Install using a calibrated 1/8 inch hex key or driver rated for the torque requirements of the assembly. Always verify the mating thread is clean and the correct 10-24 UNC pitch before driving. Follow applicable industry or equipment manufacturer torque guidelines; do not exceed the rated hardness limits of the fastener by over-torquing. Ensure the mating component material is compatible with the black oxide alloy steel to avoid galvanic corrosion in wet or outdoor environments.
