Value Collection R63003443 Hex Socket Cap Screw 1/4-20 Unc

Product Description

The VALUE COLLECTION R63003443 is a hex socket cap screw designed for fastening applications that require a compact, recessed drive. Threaded to 1/4-20 UNC with a 5/8-inch length under head, this screw accepts a 3/16-inch hex key for installation. The fastener is manufactured from Grade 316 stainless steel, providing strong resistance to corrosion in wet, chemical, or marine environments. It is well suited for maintenance, mechanical assembly, and equipment fabrication tasks performed by plumbers, HVAC technicians, electricians, and general tradespeople who need a reliable corrosion-resistant fastener.

This screw is a standard choice for indoor and outdoor mechanical assemblies where exposure to moisture, mild chemicals, or salt air is a concern. Grade 316 stainless steel offers greater corrosion resistance than Grade 304, making it appropriate for coastal installations, process piping supports, HVAC equipment mounts, and similar trade applications. The 1/4-20 UNC thread is one of the most common unified coarse thread sizes used across mechanical and trade equipment, making this screw easy to source and straightforward to work into existing assemblies.

Key Features

• 1/4-20 UNC thread for compatibility with standard unified coarse thread tapped holes
• 5/8-inch length under head suits typical light-duty to medium-duty fastening tasks
• 3/16-inch hex drive allows use of a standard hex key or Allen driver
• Grade 316 stainless steel construction resists corrosion in wet and chemical environments
• Low-profile socket cap head fits in recessed or space-constrained installations

Compatibility

Designed as a standard hex socket cap screw for use in any application requiring a 1/4-20 UNC thread and a 3/16-inch hex drive.

Installation Notes

Installation requires a 3/16-inch hex key or Allen-style driver. Ensure the mating tapped hole is clean and free of debris before threading. Power down or de-energize any equipment before fastening components in electrical or mechanical enclosures. Avoid cross-threading by starting the fastener by hand before applying drive torque.
