Value Collection 701073PR Button Socket Cap Screw 8-32

Product Description

The VALUE COLLECTION 701073PR is a button socket cap screw designed for applications requiring a low-profile head with high clamping strength. Manufactured from alloy steel with a black oxide finish, it provides moderate corrosion resistance and a clean appearance in assembled components. The screw features an 8-32 UNC thread in a 3A fit class, a 5/16-inch length under the head, and is fully threaded. Drive engagement is a 3/32-inch hex socket. Hardness is rated at 36 to 43 HRC. Licensed machinists, millwrights, maintenance technicians, and assembly professionals install this fastener in machine frames, fixtures, panels, and equipment enclosures where a flush or recounted head profile is required.

This button socket cap screw is suited for light to medium-duty fastening in metal fabrication, machine assembly, and industrial maintenance applications. The fully threaded shank and 8-32 UNC thread pattern make it a common choice for tapped holes in aluminum, steel, and similar materials. Its compact button head reduces interference in tight clearance areas. The black oxide coating is appropriate for indoor applications where minimal surface protection is acceptable. Right-hand thread direction follows standard installation practice.

Key Features

• Low-profile button head reduces clearance interference in assemblies
• Alloy steel construction with 36 to 43 HRC hardness for reliable clamping strength
• Black oxide finish for light corrosion resistance and clean appearance
• 8-32 UNC fully threaded, 3A thread fit class for precise engagement
• 3/32-inch hex socket drive compatible with standard hex keys and socket drivers
• Conforms to ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard-specification button socket cap screw for use in any tapped 8-32 UNC thread application requiring an ANSI/ASME B18.3 and ASTM F835 compliant fastener.

Installation Notes

Installation should be performed with a calibrated 3/32-inch hex key or hex socket driver to prevent cam-out and head damage. Verify that the mating tapped hole depth and thread class are compatible before driving the screw to final torque. De-energize or lock out any powered equipment before fastener installation or removal per applicable safety procedures. Black oxide does not provide heavy corrosion protection; avoid use in high-moisture or outdoor environments without additional protective measures.
