Truss head tapping screw - #8 x 1 in - square socket - zinc plated - Fasteners & Fittings 8100STSZTRS

SKU: FIT-8100STSZTRS

#8 x 1 in zinc-plated truss head tapping screw with square socket drive and full thread for fastening light-gauge metal components, covers, brackets, and electrical hardware. Commonly used where a low-profile, wider bearing head helps hold sheet material without pulling through.

What this product is for

This #8 x 1 in tapping screw is used to fasten light-gauge metal parts in electrical and general construction work. The truss head provides a broad, low-profile bearing surface, and the square socket drive helps reduce cam-out during installation.

Use for

Use for sheet metal, electrical enclosures, covers, brackets, straps, and similar hardware where a zinc-plated steel screw is suitable for indoor service. It is commonly selected when you need more head coverage than a pan or flat head screw.

Avoid for

Avoid for corrosive outdoor environments, stainless-required applications, or structural connections unless the assembly specification calls for this exact fastener. Do not substitute for bonding or grounding hardware unless specifically approved for that purpose.

Best for

Best for electricians, panel builders, and contractors securing thin metal components where clean fit-up and repeatable drive engagement matter. The square recess is a practical choice for production work and service calls.

Installed in

Typically installed in indoor commercial, institutional, and residential electrical work, including panel accessories, device mounting hardware, and light sheet-metal assemblies.

Why this product exists

This screw combines a truss head profile, square socket drive, and full thread to simplify fastening in thin metal applications. Compared with narrower head styles, the truss head spreads clamping force over a wider area, which can help on slotted or thinner materials.

Compared with similar products

Compared with flat head screws, this truss head does not sit flush and is better where a wider top bearing surface is preferred. Compared with pan head screws, the truss head is typically broader and lower in profile. Zinc plating is commonly used for indoor dry locations, while stainless or specialty coatings are typically chosen for harsher environments.
