Reznor 113275 Screw

The Reznor 113275 Screw is a critical OEM replacement fastener engineered specifically for high-stress applications within Reznor unit heaters. This #10-32 x 1/2" slotted hex screw is designed to offer maximum torque retention in environments subject to constant thermal expansion and mechanical vibration. Unlike generic hardware, the 113275 is manufactured with a corrosion-resistant coating that prevents seizing in the high-heat zones of the burner assembly and heat exchanger panels. Its precision threading ensures a gastight seal on access doors and robust structural integrity for mounting brackets. As a seasoned technician knows, using genuine Reznor heater parts like this zinc-plated hex head screw is essential for maintaining the UL and ETL certifications of the equipment. Whether you are performing annual preventative maintenance or securing a new venter motor, these self-drilling HVAC screws provide the reliable grip needed to prevent panel rattle and ensure safe operation across UDAP and UDZ series units.

• OEM Precision: Direct replacement for part number 113275, ensuring perfect thread pitch and engagement for Reznor cabinetry.
• Vibration Resistance: Specifically engineered to maintain clamping force despite the operational harmonics of axial fans and blowers.
• Corrosion Protection: High-grade finish resists oxidation in moisture-prone combustion environments.
• Structural Integrity: The #10 gauge steel construction handles high-torque installation without head stripping or shearing.

Is this screw compatible with the newer Reznor UDX series?
Yes, the Reznor 113275 is a standard fastener used across multiple generations of unit heaters, including the UDX and UDZ models, for securing panels and internal components.

Can I use a standard hardware store #10 screw instead?
While the size may look similar, OEM fasteners are rated for specific heat tolerances and vibration resistance required for HVAC equipment safety standards.

What tool is required for installation?
This part features a slotted hex head, allowing it to be driven by a standard 5/16" nut driver or a flat-blade screwdriver in tight clearances.
