L H Dottie Co DDSMS101 Round Head Tapping Screw 10x1

Product Description

The L H DOTTIE CO DDSMS101 is a number 10 by 1 inch round head tapping screw designed for fastening into pre-drilled or self-piercing applications in light-gauge metal and similar materials. Tapping screws cut or form their own threads as they are driven, eliminating the need for a separately tapped hole. This fastener is sold individually and is suited for use by electricians, HVAC technicians, plumbers, and other trade professionals who need a reliable, single-piece fastener for panel, bracket, and equipment assembly work.

This screw is appropriate for residential and light commercial trade applications where a round head profile is required for clearance or aesthetic reasons. The number 10 diameter and 1 inch length make it a common choice for securing sheet metal components, electrical enclosures, junction boxes, and HVAC equipment panels. It is intended for installation into metal substrates where thread engagement is needed without a pre-tapped hole.

Key Features

• Round head profile provides a low-profile bearing surface for panel and enclosure fastening
• Self-tapping design cuts threads on installation, no pre-tapped hole required
• Number 10 diameter by 1 inch length suits common trade fastening applications
• Sold individually, allowing precise quantity control for service and repair work

Compatibility

Designed as an OEM-style replacement and general-use fastener for light-gauge metal panels, electrical enclosures, and HVAC equipment assemblies requiring a number 10 round head tapping screw.

Installation Notes

This fastener is installed by electricians, HVAC technicians, and general trade professionals using a standard Phillips or slotted screwdriver or a power driver with the appropriate bit. Always de-energize electrical equipment and follow lockout/tagout procedures before fastening or removing screws on live panels or enclosures. Ensure the substrate material and thickness are appropriate for the screw diameter and thread engagement length. Follow applicable NEC or local code requirements when fastening electrical enclosures or equipment covers.
