L H Dottie Co HWSMS10112 Hex Washer Head Screw

Product Description

The L H Dottie Co HWSMS10112 is a 10 x 1-1/2 inch hex washer head sheet metal screw designed for fastening sheet metal, light steel framing, and similar materials in trade applications. The hex washer head design allows installation with a standard hex driver or nut driver, providing a secure, high-torque drive without damaging the workpiece surface. Sold individually, this fastener is a standard item in HVAC, electrical, and general mechanical trade work where reliable sheet metal attachment is required.

This screw is commonly used in HVAC duct fabrication and equipment enclosure assembly, electrical panel and junction box mounting, and general sheet metal work. The 10-32 or self-tapping No. 10 shank size and 1-1/2 inch length make it suitable for moderate-thickness gauge sheet metal applications encountered in residential and light commercial mechanical and electrical installations.

Installation Notes

Installed by HVAC technicians, electricians, and sheet metal workers using a nut driver or hex-head power bit. De-energize all electrical equipment before driving fasteners near live components. Follow applicable NEC or mechanical code requirements for fastener spacing and material compatibility. Do not overdrive — the washer head can distort thin gauge sheet metal if excess torque is applied.
