Value Collection 40260 Hex Socket Cap Screw 1/2-20 Unf

Product Description

The VALUE COLLECTION 40260 is a 1/2-20 UNF hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. The screw features a 3/8-inch hex drive socket head and measures 2 inches in length under the head. It is fully threaded along its entire shank. Constructed from alloy steel with a black oxide finish, the 40260 offers improved corrosion resistance and reduced light reflection compared to bare steel fasteners. This type of fastener is typically installed by machinists, millwrights, maintenance technicians, and mechanical contractors working in industrial and commercial settings.

The 40260 is suited for use in equipment assemblies, machine frames, jigs, fixtures, and general industrial fastening where a fine-thread, high-strength socket cap screw is required. The 1/2-20 UNF thread pitch provides finer thread engagement than its coarse-thread equivalent, making it a preferred choice in applications requiring precise torque control or resistance to loosening under vibration. It is sold in a minimum order quantity of 25 pieces per transaction.

Key Features

• 1/2-20 UNF fine thread for tight thread engagement and vibration resistance
• Fully threaded shank along the entire 2-inch length under head
• 3/8-inch hex socket drive for use with standard hex keys or socket drivers
• Alloy steel construction for high tensile strength
• Black oxide finish for moderate corrosion resistance and reduced glare
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard 1/2-20 UNF socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574, suitable for use in any application requiring a fine-thread alloy steel socket cap screw of this thread size and length.

Installation Notes

Installation requires a 3/8-inch hex key or hex socket driver. Power down and de-energize any equipment before servicing fastened assemblies. Do not exceed the torque specification called out in the equipment manufacturer's service documentation. Black oxide fasteners used in wet or outdoor environments may require additional corrosion protection such as thread sealant or lubricant.
