Value Collection KP25098 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION KP25098 is a hex socket cap screw designed for secure fastening in mechanical assemblies, industrial equipment, and maintenance applications. It features a 1/4-20 UNC thread size, a 3/16-inch hex drive, and is fully threaded along its 7/16-inch length under the head. Constructed from alloy steel with a black oxide finish, this fastener provides solid tensile strength and basic corrosion resistance for interior and general-purpose use. It meets ASME/ANSI B18.3 and ASTM A574 standards, making it appropriate for applications where dimensional and strength conformance are required. Installation is performed with a standard hex key or Allen wrench.

This screw is suited for use in light machinery, equipment frames, jigs, fixtures, and general mechanical assemblies in both residential and commercial maintenance environments. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes, making this fastener a frequent replacement and stocking item for maintenance technicians, millwrights, and general tradespeople. The compact 7/16-inch under-head length fits shallow fastening applications where full-length screws would bottom out or protrude. Sold in multiples of 25 per order.

Key Features

• 1/4-20 UNC fully threaded for consistent thread engagement along the full shank length
• 3/16-inch hex socket drive compatible with standard Allen wrenches and hex bit drivers
• Alloy steel construction provides higher tensile strength than standard carbon steel fasteners
• Black oxide finish offers mild corrosion resistance and reduces light reflection in service environments
• Meets ASME/ANSI B18.3 and ASTM A574 dimensional and mechanical standards
• Minimum order quantity of 25 units suits stocking and bulk maintenance use

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for general mechanical fastening applications where ASME/ANSI B18.3 and ASTM A574 conformance is required.

Installation Notes

Install using a 3/16-inch hex key or Allen driver. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque range for 1/4-20 alloy steel fasteners as specified by the applicable mechanical or equipment standard. Black oxide finish provides limited corrosion protection and is not recommended as the sole protection in wet or outdoor exposure environments.
