Value Collection 88546502 Button Socket Cap Screw 8-32 X 1/4

Product Description

The VALUE COLLECTION 88546502 is a button socket cap screw designed for applications requiring a low-profile fastener with a clean, flush appearance. Manufactured from alloy steel with a black oxide coating, this screw offers solid corrosion resistance and hardness in the 36 to 43 HRC range. The 8-32 UNC thread runs right-hand with a 3A thread fit class for consistent, reliable engagement. The 3/32 hex socket drive accepts a standard hex key, making installation straightforward in confined spaces where a low head height is required. This fastener is suited for machine assembly, tooling fixtures, panel mounting, and general mechanical work performed by machinists, millwrights, and maintenance technicians.

This screw is commonly used in light machinery, enclosures, brackets, and fabricated assemblies where a button head profile is preferred over a standard socket cap style. The 1/4 inch length under the head suits thin stock and shallow-tapped applications. Sold in a pack of 50, this fastener is appropriate for production assembly, shop stocking, and service repair scenarios where consistent dimensional conformance to ANSI/ASME B18.3 is required.

Key Features

• Button head profile provides low-profile, finished appearance in visible or tight clearance assemblies
• Alloy steel construction with 36 to 43 HRC hardness for reliable clamping force
• Black oxide finish improves corrosion resistance in dry and mildly humid environments
• 3/32 hex socket drive compatible with standard inch hex keys and drivers
• ANSI/ASME B18.3 fastener standard ensures dimensional consistency
• Pack of 50 supports production runs, restocking, and multi-unit repairs

Compatibility

Designed as an OEM-style replacement or stock fastener for any application requiring an 8-32 UNC button socket cap screw with a 1/4 inch length under the head conforming to ANSI/ASME B18.3.

Installation Notes

Installation is performed with a 3/32 inch hex key or ball-end driver. Verify that the tapped hole meets 8-32 UNC 3B class tolerances before installation to ensure proper thread fit. De-energize or lock out any machinery before replacing fasteners in live assemblies. Do not exceed the rated torque range for an 8-32 alloy steel screw in the base material being fastened.
