M4 X 12mm Spring Dowel Pins (Dia:4.3mm Length: 12mm)

Diameter: 4.3mm
Length: 12mm
Material: Carbon Steel

Spring Dowel Pin (Slotted Spring Pin) is a flexible fastening and locating component designed to provide secure alignment and shock absorption in mechanical assemblies. Made from high-quality spring steel, it features a longitudinal slot that allows the pin to compress during installation and expand after insertion, ensuring a tight and vibration-resistant fit.

What Makes It Different

Unlike solid dowel pins, spring dowel pins can compress and adapt to hole tolerances, making installation easier and eliminating the need for extremely tight machining. The spring action also helps absorb shocks and resist loosening under dynamic loads.

Applications

Commonly used in automotive assemblies, machinery, gear systems, agricultural equipment, tools, and general engineering applications, where reliable positioning, vibration resistance, and ease of installation are important.
