Starrett No. 91 Tap Wrenches are strong and well proportioned. They are nicely finished and the gripping surfaces are properly tempered. They will firmly hold square or round shanks. Plunger operated by a knurled sleeve. The spring inside the sleeve causes the plunger to back off when pressure is removed.
NOTE: The round shanks can be gripped, but care must be used. Excessive pressure may break the moveable V-jaw.
