BESSEY STC-HH20 Horizontal Clamp (Size 20) — Automatic Height Adjustment, 1,100 N

The BESSEY STC-HH20 Horizontal Clamp offers robust horizontal clamping on a dedicated base plate, optimised for repeatability and short cycle times in workshop and production environments

• Automatic clamping height adjustment
• Max. clamping force 1,100 N
• Size 20 with 167 mm jaw length
• Adjustable spindle range 26–31.75 mm

Consistent clamping that cuts cycle time

The combination of automatic clamping height adjustment and a rated 1,100 N clamping force delivers dependable holding power with minimal operator intervention. Automatic height compensation reduces the need for manual readjustment when part thickness varies, so set-up errors and rework are lowered and fixture throughput is improved. Efficiency gains arise from fewer handling steps and from the clamp's ability to maintain consistent pressure across repetitive cycles, which is especially beneficial in medium-volume production and jigs where repeatability matters.

Compact dimensions for flexible fixture design

Designed as a horizontal base-plate clamp, the unit features a jaw length of 167 mm (L1) and an adjustable spindle range of 26–31.75 mm (M), enabling secure positioning across a variety of workpiece profiles. Additional measured points — A 10 mm, B 45 mm, C 13 mm, E 20 mm, H1 25 mm, I 10 mm, N 42 mm, P 45 mm — support precise planning when integrating the clamp into existing tooling. The modest footprint and clearly defined dimensions make the device straightforward to implement on modular tooling boards and bespoke fixtures, allowing engineers to predict spatial requirements and ensure reliable clearance for adjacent operations.

Built for workshop reliability and straightforward integration

Manufactured by BESSEY, this horizontal clamp is intended for frequent use in both trade workshops and light industrial settings where dependable clamping and rapid turnaround are required. The mechanism is engineered for low maintenance and long service life; routine checks and lubrication prolong operational performance. Its horizontal base-plate format facilitates mounting in standard fixture layouts and supports modular assembly processes. As a component in an optimised workholding strategy, the clamp contributes to reduced cycle variation and improved downstream quality outcomes.
