GripSpan is a double-sided self-tightening universal wrench made of chrome-vanadium steel with a unique tooth profile system designed to grip and turn screws and nuts without manual adjustment. The product is available in two variants – Variant 1 covers 3–8 mm on one side and 8–17 mm on the other, while Variant 2 covers 8–13 mm on one side and 14–22 mm on the other.

GripSpan fits a wide range of screw sizes across automotive, machinery, and home repairs, and its polished and plated surface provides excellent corrosion resistance.

Wrong Spanner Size. Again. And You Don't Have Time to Search Through the Whole Toolbox.

Having the right spanner for every screw size requires either a large, heavy wrench set or repeated stops to switch tools.

A multifunctional spanner with a self-tightening mechanism solves this in one – one wrench for most standard screw sizes, always ready in your pocket or tool belt. GripSpan is designed for exactly that.

Self-Tightening. No Adjustments. Just Turn.

The self-tightening mechanism in GripSpan automatically grips around the sides of the screw or nut when pressure is applied – without you needing to adjust the width manually.

The unique tooth pattern holds firm without rounding off the screw head, reducing the risk of damage to fasteners during repeated use.

Features That Make GripSpan a Versatile Hand Tool

Double-sided design in two variants - Variant 1 has 3–8 mm on one side and 8–17 mm on the other – suitable for smaller screws and standard sizes. Variant 2 has 8–13 mm on one side and 14–22 mm on the other – suitable for medium to larger nuts and bolts. Together, the two variants cover the vast majority of standard screw sizes.

Self-tightening mechanism - The mechanism automatically adapts to the size of the screw or nut upon application, providing a stable grip without manually dialing in the width – a great time-saver when working with many different sizes.

Unique tooth profile in hardened chrome-vanadium steel - The tooth profile is designed to grip the screw head with a high contact surface area, delivering steady torque without rounding off the edges, which is especially important when working with worn or hard-to-reach screws.

Polished and plated surface finish - The fully polished and plated surface protects the steel body against rust and corrosion during normal use and gives it a well-crafted appearance.

Compact and lightweight - With a length of 145–160 mm and a weight of 35–70 g, GripSpan takes up minimal space in the toolbox, tool belt, or jacket – always ready without weighing you down.

Suitable for These Situations and Areas of Use

Car repair and vehicle maintenance - Covers the most common screw sizes found in a car's engine, chassis, and interior – ideal for quick jobs under the bonnet and at the roadside.

Machinery and industrial maintenance - Suitable for mechanical equipment, pumps, valves, and industrial fasteners where a wide size range is needed without changing wrenches.

Home repairs and DIY - Used for assembling furniture, plumbing work, and general home repairs where standard screw sizes vary.

Portable tool solution - Its compact size makes GripSpan ideal to keep in the car, backpack, or tool belt as a quick and versatile alternative to a full spanner set.

How to Use GripSpan

• Select the correct variant and correct end for the current screw size – Variant 1: 3–8 mm or 8–17 mm / Variant 2: 8–13 mm or 14–22 mm.
• Place GripSpan around the screw head or nut and apply pressure against the side of the fastener.
• The self-tightening mechanism grips automatically – turn clockwise to tighten and anti-clockwise to loosen.

Important to Know

• Always use the correct end for the current size to ensure the best grip and minimise the risk of rounding.
• Avoid using GripSpan on damaged or heavily rusted screws where the risk of rounding off is exceptionally high.
• Actual colour may appear slightly different depending on monitor settings and lighting.
• Small variations in dimensions may occur due to manual measurement.
