Value Collection 011027PR Hex Socket Cap Screw 3-48 Unc

Product Description

The VALUE COLLECTION 011027PR is a hex socket cap screw designed for precision fastening applications requiring a compact drive interface and reliable clamping force. It features a 3-48 UNC thread form with a 1/4-inch length under head and is fully threaded along its entire shank. The 5/64-inch hex drive accepts a standard hex key or Allen driver. Constructed from alloy steel with a black oxide finish, it delivers solid mechanical strength and modest corrosion resistance in controlled environments. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for precision mechanical assemblies, instrumentation, and light machinery.

This screw is suited for applications where a low-profile socket head and fine thread engagement are required. Typical use cases include electronics enclosures, optical equipment, instrument panels, and small mechanical subassemblies where torque must be applied in a confined space. The fine 3-48 UNC thread pitch provides strong thread engagement in thin materials or tapped holes with limited depth. Installers in manufacturing, maintenance, and mechanical assembly environments will find this fastener appropriate for close-tolerance work.

Key Features

• 3-48 UNC thread size with full threading along the shank
• 1/4-inch length under head for low-profile installations
• 5/64-inch hex socket drive compatible with standard Allen keys
• Alloy steel construction for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 standards

Compatibility

Designed as a standard 3-48 UNC hex socket cap screw suitable for tapped holes conforming to ASME/ANSI B18.3 and ASTM A574 specifications in precision mechanical and instrumentation assemblies.

Installation Notes

Installation requires a 5/64-inch hex key or Allen driver; ensure the driver is fully seated before applying torque to avoid rounding the socket. Clean and inspect the tapped hole for debris or damage before installation. Follow applicable mechanical assembly standards and do not overtorque, as small-diameter alloy screws can be susceptible to thread stripping in softer base materials. This fastener is intended for installation by qualified mechanical assemblers or maintenance technicians.
