Description
Overview:
The Timco Tec Fix Stitching Screw (Hex Head) is a heavy‐duty steel fastener for joining light section steel to steel. Sized 6.3 x 25 mm, it is engineered to clamp and seal sheet metal components and brackets where the combined steel thickness is up to 5 mm. A bonded EPDM washer helps create a weather‐resistant seal while spreading the load under the hex head. The Ruspert plated finish provides strong corrosion resistance for long service life in exposed or high‐moisture settings. Supplied in a pack of 100, these screws suit fabrication, installation, and maintenance on construction equipment and garden machinery, such as fixing guards, panels, housings, cladding, and frame members. The hex head allows positive drive with a compatible hex socket or nut‐setter.
Key Features:
- 6.3 x 25 mm steel stitching screw for light section steel‐to‐steel fastening
- Works on steel thicknesses up to 5 mm for dependable clamping and pull‐out resistance
