Value Collection 201011PR Button Socket Cap Screw 2-56

Product Description

The VALUE COLLECTION 201011PR is a fully threaded button socket cap screw designed for compact fastening applications where a low-profile head is required. Sized at 2-56 UNC with a 3/8 inch length under head, this screw is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and reduces light reflection. Hardness is rated at 36-43 HRC, meeting ANSI/ASME B18.3 and ASTM F835 standards. Drive type is hex socket, accepting a standard hex key. This fastener is suitable for use by machinists, assembly technicians, and field service professionals requiring a reliable, spec-compliant small-diameter cap screw.

This screw is commonly used in precision mechanical assemblies, electronic enclosures, instrument panels, and light-duty structural applications where a flush or near-flush head profile is preferred over a standard socket head. The 2-56 thread size is typical in small-scale assemblies found in industrial equipment, robotics, and control system housings. Right-hand thread direction and Class 3A thread fit ensure consistent engagement with standard tapped holes. Sold individually with a minimum order quantity of 100 pieces.

Key Features

• Button head profile provides a low-profile, finished appearance with a large bearing surface
• Hex socket drive accepts standard hex keys for precise torque application in tight spaces
• Alloy steel construction rated 36-43 HRC for strength in demanding fastening applications
• Black oxide finish offers mild corrosion resistance and a non-reflective surface
• Fully threaded 2-56 UNC, Class 3A fit for consistent engagement with standard tapped holes
• Meets ANSI/ASME B18.3 and ASTM F835 standards for dimensional and mechanical compliance

Compatibility

Designed as an OEM-style replacement or standard-stock fastener for any application requiring a 2-56 UNC fully threaded button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835 specifications.

Installation Notes

Installation is typically performed by machinists or assembly technicians using a properly sized hex key or hex bit driver. Ensure the mating tapped hole is clean and free of debris before driving the fastener. Do not exceed the rated torque capacity appropriate for the 2-56 thread size and alloy steel grade. Black oxide coatings do not provide heavy-duty corrosion protection; apply a supplemental lubricant or coating if the installation environment involves moisture or chemical exposure.
