The WILLIAMS COMFORT PRODUCTS QZOM30ADP is a 30 MM open-end torque wrench head designed for precision fastening in professional trade applications. It uses a dual-pin shank connection, which locks the head securely to compatible torque wrenches for controlled, repeatable torque delivery. The maximum torque rating is 413 ft-lb, making it suitable for heavy-duty fastening tasks. Technicians and mechanics working with metric fasteners in HVAC equipment, mechanical systems, or industrial assemblies will find this head a reliable addition to a torque wrench set.
This torque wrench head is intended for use in professional service environments where metric fastening precision is required. The open-end head design allows access to fasteners in confined or obstructed locations where a closed or ratcheting head cannot fit. It is sold individually and is appropriate for licensed HVAC technicians, plumbers, and mechanical contractors who routinely work with large metric hardware on equipment installations, maintenance, and service calls.
Designed as an OEM-style replacement or supplemental torque wrench head for professional torque wrench systems that accept dual-pin Z-shank accessories in compatible drive sizes.
Installation and use should be performed by qualified trade professionals familiar with torque wrench procedures. Verify that the torque wrench handle and head shank type are compatible before applying load. Do not exceed the 413 ft-lb maximum torque rating. Inspect the dual-pin connection for wear or damage before each use to ensure accurate torque transfer.
