HITBOX Welding Ground Clamp – Solid Brass, Screw-Lock C-Style, 400A, 2.3in Jaw

Secure grounding with a twist: HITBOX screw-lock design

In demanding welding tasks, a reliable ground connection is essential. HITBOX’s ground clamp uses a screw-type lock that twists into place and stays secure even under vibration, reducing hand fatigue and minimizing slips. Grounding becomes a confident, repeatable step in your setup.

Built from solid brass, the clamp delivers efficient current transfer and stands up to rust, corrosion, and welding spatter. The visible heft of the metal communicates durability, and the brass body promotes steady performance across environments—from busy fabrication shops to home garages.

Heavy-duty power for a wide range of welds

Designed for a 300A–500A range, this clamp handles everything from light sheet metal to thick structural components. The jaw opens up to 2.3 inches, enabling you to secure larger pieces with confidence. Its 1.65 lb weight emphasizes a solid, non-hollow construction that can contribute to steadier arc initiation.

Three-set screws form a three-point cable fastening system that grips the cable from multiple angles. This design aims for a firm, low-slip connection that remains stable as you work, reducing the need to re-tighten during runs.

Broad welder compatibility and practical contents

The clamp is designed to work with TIG, MIG, and MMA/stick welding setups, making it a versatile choice for fabrication, repair tasks, and workshop use. The package includes a copper connector sheet and a black insulation cover to simplify a clean, safe, and durable installation.
