Value Collection 701017PR Button Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION 701017PR is a button socket cap screw designed for precision fastening applications where a low-profile head is required. Manufactured from alloy steel with a black oxide coating, this screw provides corrosion resistance and a clean, finished appearance. The hex socket drive allows for high torque installation in tight spaces where a standard driver cannot reach. The 2-56 UNC thread and 1-inch length under head make it well-suited for instrumentation, electronics enclosures, and light mechanical assemblies. Thread fit is Class 3A, confirming tight, precise mating tolerances. Hardness ranges from 36 to 43 HRC, meeting ANSI/ASME B18.3 and ASTM F835 standards.

This button socket cap screw is used in residential and commercial applications where a flush or near-flush fastener head profile is needed. Common installation scenarios include panel assembly, electronic chassis work, jig and fixture construction, and equipment enclosures. The black oxide finish reduces light reflection and provides mild surface protection. The screw is fully threaded along its 1-inch shank and features a right-hand thread direction, following standard UNC threading conventions. This screw is sold individually but requires a minimum order quantity of 100 units.

Key Features

• Button head profile provides low-profile, flush-style installation
• Hex socket drive allows high-torque fastening in confined spaces
• Alloy steel construction with 36-43 HRC hardness for strength and durability
• Black oxide coating for mild corrosion resistance and reduced glare
• Fully threaded 1-inch shank with Class 3A UNC thread fit
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-production button socket cap screw compatible with 2-56 UNC threaded applications in mechanical assemblies, electronic enclosures, and instrumentation panels.

Installation Notes

Installation is typically performed by mechanical assemblers, electricians, or instrumentation technicians using an appropriately sized hex key or Allen driver. Ensure the mating threaded hole is clean and free of debris before installation. Do not overtighten, as over-torquing small-diameter fasteners can cause thread stripping or head shear. Follow applicable mechanical assembly standards for your application.
