PILOT PIN
PILOT PIN (TPS PIN)
📌 Overview
The Stainless Steel Pilot Pin (TPS Pin) is a precision alignment and positioning fastener used to locate, guide, and secure components during assembly.
It is commonly used in tooling fixtures, welding jigs, fabrication setups, sheet metal assemblies, and structural alignment tasks.
The pin features a tapered lead-in (pilot) for easy insertion, allowing fast and repeatable alignment of holes or components. Its straight shank provides stable positioning, while stainless steel construction ensures high strength, wear resistance, and corrosion durability.
Available in SS304 (A2) and SS316 (A4) grades, Pilot Pins are ideal for both industrial and outdoor/marine environments.
