Value Collection 011031PR Hex Socket Cap Screw 3-48 Unc

Product Description

The VALUE COLLECTION 011031PR is a hex socket cap screw engineered for precision fastening in tight-clearance applications. Manufactured from alloy steel with a black oxide finish, this fastener features a 3-48 UNC thread and measures 1/2 inch in length under the head. It is fully threaded and driven with a 5/64 inch hex key. Alloy steel construction delivers high tensile strength in a compact form factor. The black oxide coating provides a base level of corrosion resistance and reduces light reflection in finished assemblies. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards.

The 011031PR is suited for light mechanical assemblies, instrument components, electronics enclosures, and precision equipment where a low-profile, high-strength socket cap screw is required. The 3-48 UNC thread is commonly used in small machine parts, jigs, fixtures, and tooling plates. Fully threaded design maximizes thread engagement across the entire shank length. These screws are typically installed by machinists, assembly technicians, and maintenance professionals working on fine-threaded mechanical systems.

Key Features

• 3-48 UNC thread for use in small precision assemblies and instrument-grade applications
• 1/2 inch length under head with full threading for maximum thread engagement
• 5/64 inch hex drive for use with standard hex keys or Allen drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance and a clean, non-reflective appearance
• Conforms to ASME/ANSI B18.3 dimensional standards for socket cap screws

Compatibility

Designed as a standard-dimension socket cap screw conforming to ASME/ANSI B18.3, suitable for use in any tapped hole or threaded insert accepting a 3-48 UNC thread.

Installation Notes

Installation requires a 5/64 inch hex key or socket driver. Ensure the mating tapped hole is clean and free of debris before driving. Apply appropriate thread-locking compound if vibration resistance is required. Do not exceed the rated torque range for size 3 alloy steel fasteners as specified by ASME standards.
