Value Collection 353-2304-01 Button Socket Cap Screw 10-32

Product Description

The VALUE COLLECTION 353-2304-01 is a fully threaded button socket cap screw designed for applications requiring a low-profile head and high fastener strength. Built from alloy steel with a black oxide finish, this screw measures 1/4 inch under the head and carries a 10-32 Unified National Extra Fine thread. It drives with a Torx Plus IP25 bit, which reduces cam-out compared to standard hex socket drives. Hardness is rated at 39-44 HRC, making it suitable for medium-to-high-strength fastening tasks in tight clearance assemblies. Licensed electricians, mechanical technicians, and fabricators install this fastener type across a wide range of equipment and panel work.

This screw fits applications where a conventional hex socket cap screw head height would interfere with mating parts or enclosure walls. The button head profile distributes clamping load over a broader bearing surface, which helps prevent pull-through in thinner materials. Typical uses include control panel assembly, enclosure fabrication, HVAC component mounting, and general mechanical subassembly work where a clean, low-profile fastened joint is required. The black oxide coating provides mild corrosion resistance and reduces light reflection in finished assemblies.

Key Features

• 10-32 Unified National Extra Fine (UNRF) thread, right-hand direction, Class 3A fit for close-tolerance joints
• Torx Plus IP25 drive reduces cam-out and allows higher torque transfer than standard hex drives
• Button head profile lowers overall installed height and spreads bearing load
• Alloy steel construction hardened to 39-44 HRC for reliable medium-to-high-strength fastening
• Black oxide coating provides mild corrosion resistance and a low-glare matte finish
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 10-32 button socket cap screw for use in any assembly specifying a UNRF Class 3A thread, ANSI/ASME B18.3 geometry, and a Torx Plus IP25 drive at 1/4 inch length under head.

Installation Notes

Install with a Torx Plus IP25 bit; do not substitute a standard Torx T25 bit, as the Torx Plus profile has a tighter fit and substitution can damage the drive recess. De-energize and lock out any equipment before fastener service on electrical or control enclosures, per NFPA 70E safe work practices. Use a calibrated torque tool and follow the assembly drawing torque specification for the joint material and thread engagement depth. Inspect the mating threaded hole for cleanliness and proper thread form before installation.
