Tapping Screw · #8 x 3/4 in Pan Head Robertson Drive Zinc-Plated · Steel Self-Tapping · Fitsfast 152989

What this product is for

This #8 x 3/4 in (19 mm) pan head Robertson drive tapping screw is used for fastening electrical hardware, brackets, covers, straps, and light-gauge metal components where a self-tapping thread is required. The zinc-plated steel construction is generally selected for indoor service in dry locations.

Use for

Use for sheet metal, electrical boxes and accessories, control enclosures, fixture parts, and general-purpose fastening into pre-punched or pilot-prepared material. The pan head provides a broad bearing surface, and the Robertson drive is commonly chosen by Canadian electricians for better bit engagement during repetitive installation.

Avoid for

Avoid for corrosive, wet, or exterior environments unless the application specifically accepts zinc-plated steel. Avoid where a certified stainless or coated fastener is required, or where base material thickness and hole size call for a different thread-forming or self-drilling screw.

Best for

Best for contractors and maintenance teams needing a common #8 self-tapping screw length for indoor electrical and general fastening work. This size is typically chosen when a low-profile pan head and square drive are preferred for control and reduced cam-out.

Installed in

Typically installed in commercial, institutional, and residential electrical work, including panels, device boxes, metal brackets, utility rooms, and shop fabrication. Actual suitability depends on substrate thickness, pilot hole condition, and local code requirements.

Why this product exists

This screw provides a straightforward fastening option for trades that need a common imperial size, self-tapping action, and Robertson drive compatibility. It helps reduce the need for separate nuts in many light-duty fastening tasks and supports faster installation in repetitive work.

Compared with similar products

Compared with Phillips pan head tapping screws, a Robertson drive is typically preferred in Canada for improved driver retention. Compared with self-drilling screws, this product is generally used where the material is thin enough or where a pilot or existing hole is already present. Zinc plating offers basic corrosion resistance, but it is not a substitute for stainless steel in harsher environments.
