Value Collection 011257P Hex Socket Cap Screw 3/8-16 Unc

Product Description

The VALUE COLLECTION 011257P is a hex socket cap screw designed for secure, high-torque fastening in mechanical, industrial, and trade applications. Manufactured from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and surface hardness suited for demanding environments. The screw features a 3/8-16 UNC thread size, a 1-1/4 inch length under head, and is fully threaded from tip to head. The 5/16 inch hex socket drive allows for torque application using a standard hex key or Allen driver. At 0.05 pounds, this is a compact, precision fastener built to ASME/ANSI B18.3 and ASTM A574 standards.

This cap screw is commonly used in mechanical assemblies, equipment mounting, HVAC component brackets, electrical enclosures, and general industrial fabrication. The 3/8-16 UNC coarse thread pattern makes it well suited for use in steel, cast iron, and aluminum tapped holes where reliable clamping force is required. It is appropriate for both original equipment assembly and field repair work performed by machinists, millwrights, HVAC technicians, electricians, and maintenance professionals. Minimum order quantity is 100 pieces per order.

Key Features

• 3/8-16 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded along the 1-1/4 inch length under head for maximum thread engagement
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• 5/16 inch hex socket drive accepts standard hex keys and socket drivers
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 3/8-16 UNC hex socket cap screw suitable for any application requiring an ASME/ANSI B18.3 compliant alloy steel fastener with a 1-1/4 inch length under head.

Installation Notes

Installation should be performed using a correctly sized 5/16 inch hex key or Allen-head driver to prevent drive rounding. Ensure the tapped hole is clean and free of debris before installation. When installing into blind holes, verify thread depth is sufficient for full engagement. Alloy steel fasteners with black oxide finish are not intended for prolonged exposure to outdoor moisture without additional corrosion protection.
