The VALUE COLLECTION R63283643 is an 18-8 stainless steel thumb screw with an oval head profile and a 3/8-16 UNC thread. It measures 2 inches in overall length, with a head diameter of 0.83 inches and a head height of 0.95 inches. The 18-8 stainless steel construction provides solid corrosion resistance, making it suitable for use in wet, humid, or outdoor environments. This fastener is designed for tool-free hand tightening in applications where frequent removal or adjustment is required. Tradespeople, technicians, and maintenance crews use this style of thumb screw where panel access, equipment covers, or adjustment fixtures need to be removed and reinstalled regularly.
The R63283643 thumb screw is appropriate for light to medium-duty fastening applications across HVAC, electrical, plumbing, and general mechanical service work. The oval head style provides a smooth, rounded grip surface well suited to panel covers, access doors, junction enclosures, and equipment housings. The UNC thread standard ensures broad compatibility with standard inch-pattern tapped holes and standard hardware. This fastener is sold individually, making it a practical replacement option for a single worn or missing thumb screw without requiring a bulk purchase.
Designed for use in any application requiring a 3/8-16 UNC inch-standard tapped hole with an oval-head thumb screw. Suitable for HVAC access panels, electrical enclosures, equipment covers, and mechanical fixtures that accept a 3/8-16 fastener.
Install by hand into a pre-tapped 3/8-16 UNC hole; no tools are required for standard assembly or removal. Inspect the mating tapped hole for thread damage or corrosion before installation to ensure full thread engagement. When used on electrical enclosures, de-energize the equipment per NEC guidelines before removing or replacing panel fasteners. Do not overtighten by using tools, as the oval head is designed for hand-torque applications only.
