Rheem pd637241 Sheet Metal Screw 8-18 X 3/8 in Pack of 50

Product Description

The RHEEM pd637241 is a pack of 50 sheet metal screws sized 8-18 x 3/8 inch, designed for use in HVAC equipment assembly and service. Sheet metal screws in this size class are a standard fastener in HVAC cabinet and component work, used to secure panels, brackets, and sheet metal components on air handlers, furnaces, and condensing units. Licensed HVAC technicians and service professionals keep these on hand for panel reinstallation and in-field repairs where OEM fastener specs are required.

This 50-piece pack is suited for residential and light commercial HVAC service applications. The 8-18 thread designation is a coarse self-tapping thread commonly used on HVAC sheet metal gauge panels and enclosures. Having an OEM-matched fastener pack on the service vehicle prevents delays when cabinet panels or access doors must be re-secured after component replacement or inspection.

• 8-18 x 3/8 inch self-tapping sheet metal screw size for HVAC panel and bracket fastening

Installation Notes

Sheet metal screws of this type are installed by HVAC technicians using a standard Phillips or hex-head driver, depending on the screw head style. Power down the unit and follow lockout/tagout procedures before removing or reinstalling any cabinet panels or access covers. Avoid overtightening, which can strip the sheet metal or damage panel flanges. Follow applicable local codes and manufacturer service documentation when reassembling equipment enclosures.
