M3 Shear Pins

Perfect fit for my rocket’s dual-deployment setup—the nylon sheared cleanly during testing, exactly as intended. I’d buy these again for their reliability in high-stress launches.

I used these as shear pins for my dual-deployment rocket and the M3 size fit perfectly in the pre-tapped holes. The nylon material snapped cleanly during testing at the expected pressure, giving me confidence for the actual flight.

These nylon screws snap right at the thread like they're supposed to, so my nose cone pops clean instead of dragging the whole stack down. Getting the tap size matched took a minute, but once dialed in they've held perfect on every flight.
