The Wera 3816R is a stainless bit holding screwdriver designed for working with stainless steel fixings, eliminating the risk of extraneous rust caused by contact between standard tool materials and stainless screws. At the heart of this screwdriver is Wera's Rapidaptor quick-release chuck, which allows fast bit changes without the need for additional tools. Bits are held securely during use, and the free-turning sleeve aids accurate positioning and guiding when used alongside a power tool. The Kraftform Plus handle is ergonomically shaped for comfortable extended use, with hard gripping zones that support higher working speeds and soft zones that maximise torque transfer. This combination reduces hand fatigue and the likelihood of blisters or calluses during prolonged work. The screwdriver accepts standard ¼" hexagon shank bits conforming to DIN ISO 1173-C 6.3 and E 6.3 (ISO 1173), making it compatible with a wide range of commonly available bits. Ideal for contractors, plumbers, and fabricators working with stainless steel fixings where rust contamination is a concern.
