Value Collection 015145PR Hex Socket Cap Screw 1/4-20 Unc

Product Description

The Value Collection 015145PR is a hex socket cap screw designed for general industrial and mechanical fastening applications. It features a 1/4-20 UNC thread size and measures 1/2 inch in length under the head, with full threading along the entire shank. The drive is a 3/16-inch hex socket, accepting a standard Allen or hex key. Constructed from alloy steel with a black oxide finish, this fastener delivers solid corrosion resistance and surface hardness suited for demanding assembly environments. It meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards.

This cap screw is suited for use in machinery assembly, equipment repair, and structural fastening tasks where a recessed socket drive is required. The fully threaded shank allows for maximum thread engagement across the full length of the fastener, making it appropriate for thinner material applications or where a nut is used. It is a common choice for maintenance technicians, machinists, and industrial assembly professionals working with steel or aluminum components.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes and hardware
• Fully threaded shank maximizes thread engagement along the entire 1/2-inch length
• 3/16-inch hex socket drive accepts standard Allen keys and hex bit drivers
• Alloy steel construction provides high tensile strength for demanding fastening applications
• Black oxide finish offers moderate corrosion resistance and reduces light reflection
• Meets ASME/ANSI B18.3, ASTM A574, and IFI 124 fastener standards

Compatibility

Designed as an OEM-style replacement or standard-use fastener for any application requiring a 1/4-20 UNC hex socket cap screw with a 1/2-inch length under head and fully threaded shank.

Installation Notes

Installation is performed with a 3/16-inch hex key or Allen driver. Ensure the mating tapped hole or nut meets 1/4-20 UNC thread specifications before installation. Apply thread-locking compound or washers as required by the assembly specification. Do not overtighten, as alloy socket cap screws can be damaged if torque limits are exceeded without reference to the applicable torque table.
