STRONGHOLD Hammer Wrench

The STRONGHOLD Hammer Wrench is a heavy-duty striking wrench engineered and manufactured to the demanding performance requirements of oilfield drilling, wellhead, and BOP operations across the UAE, GCC, and wider MENA region.

Precision-forged from AISI 4145H chromium-molybdenum alloy steel — the industry standard material for downhole and surface oilfield tools — the STRONGHOLD Hammer Wrench delivers the exceptional toughness, impact resistance, and fatigue strength required for high-torque make-up and break-out of heavy-duty flange bolts, studs, and connections. Manufactured in strict compliance with API Specification 7-1 (Specification for Rotary Drill Stem Elements), every wrench in the STRONGHOLD range meets verified quality benchmarks for material properties, dimensional accuracy, and mechanical performance.

Also referred to as a slugging wrench, striking wrench, or slogging wrench, the Hammer Wrench is designed so that the wrench head engages the nut or bolt hex, while the flat striking lug on the handle is struck with a hammer to apply extreme rotational force in confined spaces — ideal for wellhead bolt flange assembly, BOP stack connections, choke and kill manifolds, and drill floor equipment maintenance across land rigs, offshore platforms, and pipeline installations.

Available in 14 sizes from HW5063 to HW5250, covering stud bolt sizes from 5/8″ through 2-1/2″, the STRONGHOLD Hammer Wrench range provides complete coverage for all standard API flange bolting sizes used on wellheads (API 6A), blowout preventers (API 16A), and subsea equipment (API 17D) throughout oilfields in Abu Dhabi, Dubai, Sharjah, Muscat, Doha, Dammam, and Riyadh.

Trusted by rig crews, maintenance engineers, and procurement teams at major operators and EPC contractors across the Middle East. Available from authorized oilfield equipment suppliers in the UAE.
