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

Product Description

The VALUE COLLECTION -33614-4 is a partially threaded hex socket cap screw designed for high-strength fastening applications. It features a 1/4-20 UNC thread size and measures 5-1/2 inches in length under the head. The screw is driven with a 3/16 inch hex key and is manufactured from alloy steel with a black oxide coating that provides mild corrosion resistance and a clean, low-reflectance finish. This screw meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding mechanical assemblies where tensile strength and dimensional accuracy are required. Sold in a package of 10.

This screw is used in a wide range of industrial and mechanical applications where a flush or low-profile head is needed and access requires a hex driver. The partially threaded shank is suited for clamping applications where the unthreaded portion must pass through a clearance hole. Typical users include machinists, millwrights, and maintenance technicians working on machinery, fixtures, tooling, and structural assemblies. The 1/4-20 UNC thread is one of the most common coarse-thread fastener sizes in North American trade work.

Key Features

• 1/4-20 UNC coarse thread for broad tool and hardware compatibility
• 5-1/2 inch length under head with partial threading for clamping applications
• 3/16 inch hex socket drive for use with standard hex keys or Allen drivers
• Alloy steel construction for high tensile strength per ASTM A574
• Black oxide finish for mild corrosion resistance and reduced surface glare
• Meets ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for use in machinery, fixtures, and assemblies that accept ASME/ANSI B18.3 socket head cap screws.

Installation Notes

Install and remove using a 3/16 inch hex key or Allen driver. Ensure the mating tapped hole is clean and free of debris before installation. Power down and de-energize any equipment before fastener service on live machinery. Torque to values appropriate for the joint material and application as specified by the equipment manufacturer or applicable engineering standards.
