Value Collection 701013PR Button Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION 701013PR is a button socket cap screw designed for precision fastening applications in metal fabrication, machine assembly, and equipment manufacturing. It features a low-profile button head driven by a hex socket, making it well-suited for installations where clearance is limited or a flush, clean appearance is required. The fastener is manufactured from alloy steel with a black oxide finish and carries a thread fit class of 3A for consistent engagement. Hardness is rated at 36 to 43 HRC. It conforms to ANSI/ASME B18.3 and ASTM F835 standards. Machinists, maintenance technicians, and mechanical assembly professionals are the primary installers.

This screw is used in light-duty to medium-duty mechanical assemblies where a standard hex socket button head profile is specified. The 2-56 UNC thread and 5/8-inch length under the head make it appropriate for thin panels, brackets, enclosures, and precision instrument housings. The black oxide coating provides mild corrosion resistance and reduces light reflection in optical or sensitive equipment environments. This SKU is sold as a single piece with a minimum order quantity of 100 units.

Compatibility

Designed as a standard 2-56 UNC button socket cap screw suitable for use in mechanical assemblies, enclosures, and precision equipment that specify ANSI/ASME B18.3 compliant fasteners with a button head hex socket drive.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using a properly sized hex key or Allen driver. Confirm the mating thread is clean and free of debris before driving. Do not exceed the torque capacity appropriate for the 2-56 thread size and alloy steel grade. Black oxide coatings do not substitute for supplemental corrosion protection in wet or outdoor environments.
