Parallel Pins with Internal Thread - 303 Stainless ISO 8733
Solid grooved pin, with parallel grooves running along the entire length. Used with blind holes, the centering step helps guide the insertion of the part. The hole must be properly sized to ensure the grooved pin achieves its intended interference fit.
Typically 3 equally spaced parallel grooves (full-length) that cause the material to displace outward, increasing retention force in the hole
Internal threading allows for easy removal of the pin. Designed for press-fit into a drilled hole — interference fit for secure placement
Thicker and stronger than lighter-duty grooved pins (such as ISO 8744).
Material: A1 / SAE Type 303
A1 / 303 Stainless pins are commonly used in machining, the automotive industry, as well as for decorative strips, door handles and oil drain valves.
For any application involving marine (salt water), use A4 / 316 Stainless Steel material.
