Adjustable M5 Pin Spanner Wrench
This 170 x 24 x 8 mm adjustable pin spanner uses two M5 bolts as pins. One bolt is locked in a fixed hex-nut pocket. The other runs in a 70 mm slot with a captive sliding-nut channel underneath, which sets the pin spacing anywhere from 20 to 90 mm. Use it on two-hole lock rings, threaded caps, pool and spa strainer lids, bike lock rings and lens rings when you don't have a dedicated spanner for that one size. The bar prints flat, so the turning force runs along the layers, and there are notches every 10 mm for repeatable settings.
