Value Collection -40233-1 Hex Socket Cap Screw 5/16-24 Unf

Product Description

The VALUE COLLECTION -40233-1 is a hex socket cap screw designed for secure, high-torque fastening in mechanical assemblies, fabrication work, and equipment maintenance applications. It features a 5/16-24 UNF thread form - a fine-pitch unified thread well suited for applications requiring precise tension control and resistance to vibration loosening. The screw is 2 inches in length under the head and is partially threaded, providing a smooth shank section that helps locate and align mated components. Drive engagement is via a 1/4-inch internal hex socket, compatible with standard hex keys and socket drivers. The alloy steel construction with a black oxide finish offers a strong strength-to-weight ratio along with moderate corrosion resistance in controlled environments.

This screw is a general-purpose industrial fastener used across a wide range of service and maintenance tasks. Typical applications include machinery assembly, HVAC equipment mounting, electrical enclosure hardware, and structural bracketing where a flush or recessed fastener head is preferred. The fine-thread 5/16-24 UNF designation makes it especially appropriate for thin-wall metal applications or where higher thread engagement strength per unit length is required. Licensed tradespeople and maintenance technicians working on commercial or residential mechanical systems will find this a standard-fit cap screw for both OEM replacement and general service use.

Key Features

• 5/16-24 UNF fine-pitch thread for vibration-resistant, precise tension fastening
• 2-inch length under head with partial threading for shank-guided component alignment
• 1/4-inch internal hex socket drive compatible with standard hex keys and bit drivers
• Alloy steel construction for high tensile strength in demanding mechanical applications
• Black oxide finish provides moderate corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard 5/16-24 UNF hex socket cap screw suitable for use in mechanical assemblies, equipment maintenance, and fabrication applications where ASME/ANSI B18.3 and ASTM A574 compliant fasteners are specified.

Installation Notes

Installation is performed using a 1/4-inch hex key or Allen-type socket driver. Ensure mating threads are clean and free of debris before driving the fastener to avoid cross-threading, especially with fine-pitch UNF threads. Always follow equipment manufacturer torque specifications for the fastener size and material grade. De-energize any electrical systems and depressurize or shut off mechanical systems before accessing fastened components in HVAC, plumbing, or electrical enclosure assemblies.
