Value Collection 011017PR Hex Socket Cap Screw 2-56 Unc

Product Description

The VALUE COLLECTION 011017PR is a hex socket cap screw designed for precision fastening in tight-clearance applications. Featuring a 2-56 UNC thread and a 5/64-inch hex drive, this screw is fully threaded along its 3/16-inch length under head. Constructed from alloy steel with a black oxide coating, it delivers solid mechanical strength and moderate corrosion resistance in indoor and controlled environments. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it a reliable choice for instrumentation, electronics assembly, and light mechanical assemblies where small-diameter precision threading is required.

This screw is suited for applications requiring a compact, high-strength fastener in a 2-56 UNC thread size. Common use cases include securing small panels, circuit board standoffs, instrumentation housings, and precision mechanical components. The socket cap head style allows installation with a hex key in confined spaces where a standard wrench or screwdriver cannot reach. This fastener is typically installed by machinists, electronics technicians, and mechanical assemblers working on light-duty precision equipment.

Key Features

• 2-56 UNC thread for fine-pitch precision fastening in small-diameter applications
• 5/64-inch hex socket drive for use with standard hex keys in tight spaces
• Fully threaded along the 3/16-inch length under head for maximum thread engagement
• Alloy steel construction provides solid tensile strength for the fastener class
• Black oxide finish offers mild corrosion resistance and reduced light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance

Compatibility

Designed as an OEM-style replacement or standard-use fastener for applications requiring a 2-56 UNC hex socket cap screw with a 3/16-inch length under head and a 5/64-inch drive.

Installation Notes

Install using a 5/64-inch hex key or appropriate socket driver. Ensure mating threads are clean and free of debris before driving to avoid cross-threading in fine-pitch 2-56 UNC tapped holes. Do not over-torque, as alloy steel screws at this diameter can be susceptible to thread stripping in softer base materials. Follow applicable assembly specifications for the equipment being serviced.
