TIMCO Advanced Coach Screw - Hex Flange Head - 12.0 x 100 - Box of 25 - 12100SCSY

The TIMco 12 x 100mm Solo Coach Screws are a versatile, heavy-duty fastener designed as a modern replacement for traditional DIN 571 coach screws. Featuring an external hex flange head, a Type 17 slash point, and a partially threaded shank, they are built to deliver strong clamping and reduced splitting in a range of materials. The aggressive point aids easy driving and minimizes torque, while the design supports high-torque applications with impact tools. Finished in zinc and yellow passivation, these screws offer improved corrosion resistance and durable performance across timber framing, landscaping, decking, fencing, stairs, roofing, gazebos, pergolas, and railway sleepers when used with appropriate plugs. The purpose-built features also include a large fixed washer to aid clamping and help prevent head pull-through, making them suitable for heavy-duty projects requiring reliable fastening over time.
