BESSEY GK gear-driven F-style wood clamp for tight spaces

The BESSEY GK gear-driven is an F-style woodworking clamp featuring a gear-driven mechanism. It delivers a clamping force of up to 2000N. The jaws are made from fiberglass, and the bar has a cross-section of 19x6mm. Designed for tight spaces, this screw clamp can be operated with one hand. It’s an authentic product from BESSEY Germany.

This F-style gear clamp is ideal for confined spaces. The abbreviation “GK” stands for “GearKlamp,” a BESSEY Germany invention. Essentially, it’s an F-style clamp with a gear mechanism.

BESSEY created this clamp to address challenging tasks in woodworking that previous F-style clamps couldn’t handle efficiently. Its primary benefits include time-saving and ensuring the precision and beauty of the finished product.

With the GK series, working effectively in extremely tight spaces is possible. BESSEY eliminated the traditional handle, relocating it to the bar, and using it as a grip.

The GK F-style gear clamp transmits clamping force through an internal gear mechanism in the clamp’s shoulder. This design makes the F-style clamp more compact, eliminating the bulky handle. Therefore, the gear-driven F-style clamp’s jaw is significantly smaller compared to the classic F-style. You can use it with just one hand in woodworking.

Another unique feature is that this clamp doesn’t damage workpieces or itself in tight spaces. The handle also serves to maintain clamping force, ensuring everything is secure. The handle design is finely crafted, and the material offers a comfortable and firm grip, even during extended use.

In terms of materials, the GK gear-driven F-style clamp is primarily made of alloy steel and plastic, mostly high-quality ABS, making it lightweight to handle. It allows for quick tightening and loosening, with smooth sliding along the bar for easy adjustments.

As for material technology, BESSEY Germany is known for its focus on quality and durability in manufacturing. From the fiberglass jaws to the high-frequency hardened steel bar, these components are exceptionally durable and resistant to impact and wear. The gear mechanism is also protected from sawdust, preventing jamming or damage, a common issue in woodworking.

The handle, featuring two contrasting plastic components, can exert up to 2000N of force (approximately 200kg). When choosing from the four typical GK clamp models, consider the following specifications:

• a: Maximum opening capacity of the jaws.
• b: Depth of the F-jaw, measured from the center of the jaw to the bar.
• x: Bar size, cross-sectional dimensions.
• MOQ: Number of GK clamps in one carton.
