Value Collection 701141PR Button Socket Cap Screw 1/4-28

Product Description

The VALUE COLLECTION 701141PR is a button socket cap screw designed for applications requiring a low-profile fastening solution with high tensile strength. Manufactured from alloy steel with a black oxide coating, this screw provides moderate corrosion resistance and reduced surface reflectivity. The 1/4-28 UNF thread with a 3A fit class ensures precise, consistent engagement. It is fully threaded with a 5/32 hex socket drive and meets ANSI/ASME B18.3 and ASTM F835 standards. Licensed tradespeople and industrial maintenance professionals commonly use this fastener in machinery, equipment panels, and assemblies where head clearance is limited.

This fastener is suited for use in mechanical assemblies, fabricated enclosures, and structural components where a button-style low-profile head is required. The UNF thread pitch is appropriate for applications demanding finer thread engagement and greater resistance to loosening under vibration. The 1-3/4 inch length under head accommodates moderate material thickness. It is a standard choice for OEM builds, field repairs, and maintenance operations across industrial, HVAC, and mechanical trade environments.

Key Features

• Button head profile provides a low-profile, finished appearance with reduced snag risk
• Alloy steel construction with 36-43 HRC hardness for high-strength fastening
• Black oxide finish offers mild corrosion resistance and a non-reflective surface
• 5/32 hex socket drive compatible with standard hex key sets
• Fully threaded 1/4-28 UNF right-hand thread with 3A fit class for consistent engagement
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as a standard 1/4-28 UNF button socket cap screw for use in any application requiring ANSI/ASME B18.3 or ASTM F835 compliant fasteners with a button head and 5/32 hex drive.

Installation Notes

Installation is typically performed by maintenance technicians, millwrights, or mechanical tradespeople using a 5/32 hex key or matching bit driver. De-energize and lock out equipment before fastener installation or removal in any live mechanical or electrical assembly. Do not exceed the rated torque range appropriate for the thread size and material being fastened. Black oxide coatings provide limited corrosion protection and may benefit from an additional lubricant or anti-seize compound in exposed or high-moisture environments.
