Value Collection -33614-3 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION -33614-3 is a hex socket cap screw designed for secure fastening in mechanical assemblies, structural fixtures, and industrial applications. It features a 1/4-20 UNC thread size with a 5-inch length under head and is partially threaded to allow controlled clamping force. The 3/16-inch hex drive accepts a standard Allen key or hex bit driver. Constructed from alloy steel with a black oxide coating, this fastener resists corrosion in moderate environments and maintains dimensional stability under torque. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for precision and load-bearing assemblies. Sold in a package of 10.

This fastener is used in a wide range of residential, commercial, and industrial applications where a recessed drive profile is required. Typical uses include machine frames, tooling fixtures, equipment enclosures, and structural brackets. The partial threading makes it well suited for applications requiring a clamped joint between two components with a clear shank passing through the top piece. Mechanical contractors, millwrights, and maintenance technicians commonly install this fastener across HVAC equipment assemblies, pump housings, and electrical enclosures.

Key Features

• 1/4-20 UNC thread size for broad compatibility with standard tapped holes
• 5-inch length under head accommodates deep or stacked assemblies
• Partially threaded shank supports precise clamping between mated components
• 3/16-inch hex drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction meets ASTM A574 for strength in load-bearing use
• Black oxide finish provides moderate corrosion resistance and reduces light reflection

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for tapped holes and applications conforming to ASME/ANSI B18.3 dimensional specifications.

Installation Notes

Installation requires a 3/16-inch hex key or hex bit driver rated for the fastener grade. Ensure the mating tapped hole meets 1/4-20 UNC thread specifications before installation. De-energize and lock out any equipment before replacing fasteners in powered assemblies. Do not exceed the rated torque range for 1/4-20 ASTM A574 alloy steel fasteners as specified by the equipment manufacturer or applicable fastener torque tables.
