Adjustable Pin Wrench Interchangeable Pins for Gland Nuts & Pulleys

An adjustable pin wrench spanner used for turning gland nuts, top-hole round nuts and wheel pulleys where a standard spanner will not fit. The divider-style adjustment and interchangeable pin pairs make it a practical option when working across different nut sizes and hole spacings.

Used for garage work, machinery maintenance, vehicle servicing and general workshop repairs, this type of wrench suits jobs where round nuts have drilled holes rather than flats. It can be useful when working on pulleys, bearing retainers and similar assemblies, and is also suitable for DIN 547 bearing nuts. For anyone carrying out regular maintenance or fitting work, it helps deal with awkward fasteners without relying on improvised tools.

The wrench adjusts by a central knurled knob, making it easier to set the span to suit the job in hand. Supplied with 8 pins in 4 pairs, it covers several pin size ranges so you can match the tool to different nuts and pulleys more closely. A 10/11mm spanner is also included for fitting or changing the pins. The interchangeable setup is useful for repeated workshop use and helps avoid having separate fixed pin wrenches for common sizes.
