Value Collection 011145P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011145P is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and equipment. It features a 1/4-20 UNC thread with a 1/2-inch length under head and is fully threaded from tip to head. The 3/16-inch hex drive accepts standard hex keys and allen wrenches. Constructed from alloy steel with a black oxide finish, this fastener delivers good corrosion resistance and a clean, low-profile appearance. It conforms to ASME/ANSI B18.3 and ASTM A574 standards. Machinists, maintenance technicians, and fabricators commonly use this screw in fixtures, machine components, and structural assemblies.

This fastener suits a wide range of industrial and mechanical applications where a compact, recessed-drive screw is required. The fully threaded 1/4-20 UNC configuration works in tapped holes or with a nut, making it versatile for both through-bolt and blind-hole installations. The black oxide alloy steel construction handles moderate load and torque demands in both shop and field environments. Typical users include maintenance mechanics, fabricators, and assembly technicians working on equipment, fixtures, and general metalwork.

Key Features

• 1/4-20 UNC thread for standard inch-system fastening applications
• Fully threaded along the 1/2-inch length under head for maximum thread engagement
• 3/16-inch hex socket drive compatible with standard hex keys and allen wrenches
• Alloy steel construction meets ASTM A574 for high-strength performance
• Black oxide finish provides mild corrosion resistance and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw for use in any tapped hole or nut application conforming to ASME/ANSI B18.3 dimensional requirements.

Installation Notes

Installation requires a 3/16-inch hex key or T-handle allen wrench. Ensure the receiving hole is properly tapped to 1/4-20 UNC before installation. Clean threads and apply thread-locking compound or anti-seize as required by the application. Do not exceed the torque capacity of the alloy steel fastener by using impact tools without torque control.
