Value Collection 837149PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION 837149PR is a hex socket cap screw designed for secure fastening in mechanical, industrial, and structural applications. Featuring a 1/4-20 UNC thread size and a 3/4-inch length under the head, this fastener is fully threaded and driven with a 3/16-inch hex (Allen) key. Constructed from alloy steel with a zinc-plated finish, it offers solid mechanical strength and corrosion resistance suitable for general-purpose use. This screw meets ASTM B695 standards, making it appropriate for environments where a recognized fastener specification is required.

This cap screw is commonly used in machine assembly, equipment maintenance, and fabrication work across industrial, commercial, and light manufacturing settings. The 1/4-20 UNC coarse thread pattern is widely compatible with tapped holes in steel, aluminum, and other common structural materials. It is a standard choice for maintenance technicians, millwrights, pipefitters, and other trades that regularly work with bolted assemblies requiring a compact, low-profile fastener head.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• Fully threaded along the 3/4-inch length under head for maximum thread engagement
• Alloy steel construction provides high tensile strength for mechanical fastening
• Zinc-plated finish adds corrosion resistance for general service environments
• 3/16-inch hex drive socket head for use with standard Allen keys or hex bit drivers
• Meets ASTM B695 fastener standard

Compatibility

Designed as a general-purpose replacement or stock fastener for any application requiring a 1/4-20 UNC fully threaded hex socket cap screw with a 3/4-inch length under head.

Installation Notes

Installation requires a 3/16-inch hex key or Allen bit driver. Ensure the mating tapped hole is clean and free of debris before threading. De-energize and lock out any equipment before replacing fasteners in live machinery per applicable OSHA lockout/tagout procedures. Do not exceed the rated torque range for 1/4-20 alloy steel fasteners as specified by your application or equipment manufacturer.
