The 50 mm Stahlberg adapter facilitates the transition between a hex bit and a 1/4" square drive. It is suitable for workshops, assembly work and regular household use, where you will appreciate a firm and reliable connection between tools.
Thanks to its precision-forged construction, the adapter achieves up to 20% higher strength compared with machined versions. The S2 chrome vanadium steel used provides excellent toughness, while heat treatment to a hardness of 61–62 HRC supports a long service life under load.
