Value Collection 011613P Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 011613P is a hex socket cap screw designed for industrial and mechanical fastening applications. It features a 1/4-20 UNC thread size with a 4-inch length under head and is driven by a 3/16-inch hex key. Constructed from alloy steel with a black oxide finish, this screw delivers strong clamping force and moderate corrosion resistance. It is partially threaded, making it well suited for applications that require a grip length under the head. Machinists, maintenance technicians, and assembly professionals typically specify this fastener when high-strength, socket-drive fastening is required in tight or recessed locations.

This screw is used across a wide range of industrial, mechanical, and equipment assembly applications. Partially threaded alloy steel cap screws in this size are commonly found in machine frames, fixture plates, tooling setups, and general structural assemblies. The black oxide coating provides a clean, low-reflectance appearance and light surface protection. This part is sold in multiples of 100, making it appropriate for production or maintenance stocking where consistent fastener supply is needed.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard inch-series tapped holes
• 4-inch length under head provides extended grip for thick-stack assemblies
• 3/16-inch hex drive for use with standard Allen keys or hex bit drivers
• Alloy steel construction for high tensile and shear strength
• Black oxide finish for light corrosion resistance and reduced surface reflectance
• Meets ASME/ANSI B18.3 and ASTM A574 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any 1/4-20 UNC tapped hole requiring a 4-inch fastener with a hex socket drive.

Installation Notes

Installation is performed using a 3/16-inch hex key or Allen driver. Ensure the mating tapped hole is clean, properly threaded, and free of debris before installation. Apply thread lubricant or thread-locking compound as required by the application specification. Do not exceed the rated torque for the fastener grade, and verify that the base material can support the clamp load before final assembly.
