Value Collection R40684446 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R40684446 is a hex socket cap screw designed for secure, flush-style fastening in mechanical assemblies. The screw features a 1/4-20 UNC thread pattern and a cylindrical head driven by a 3/16-inch hex (Allen) key. With a 3/8-inch length under the head and 18-8 stainless steel construction, it provides solid corrosion resistance in moderate-exposure environments. Machinists, millwrights, pipefitters, and maintenance technicians reach for this style of fastener when a low-profile head and high holding strength are required in confined or precision-clearance applications.

This fastener is suited for light mechanical assemblies, equipment frames, HVAC component mounting brackets, plumbing fixture hardware, and general trade maintenance work. The 1/4-20 UNC thread is one of the most common unified coarse-thread sizes in North American trade applications, making this screw a frequent stock item in service vans, fab shops, and maintenance departments. The 18-8 stainless steel grade performs well in interior environments and in areas subject to moisture or mild chemicals.

Key Features

• 1/4-20 UNC thread for broad compatibility with standard tapped holes
• 3/16-inch hex drive accepts standard Allen keys and hex-bit drivers
• 3/8-inch length under head fits shallow-clearance fastening applications
• 18-8 stainless steel construction resists corrosion in moisture-exposed environments
• Socket cap head provides a clean, low-profile finish on assembled components

Compatibility

Designed as a standard 1/4-20 UNC hex socket cap screw suitable for any tapped hole or threaded insert of matching thread specification.

Installation Notes

Installation requires a 3/16-inch hex key or Allen-style bit driver. Ensure the mating tapped hole is clean and free of debris before threading. Apply appropriate thread-locking compound or anti-seize per the assembly specification when required. Always verify torque requirements against the assembly drawing or equipment service manual before final tightening.
