HONGDUI SC-14 Desktop-Oberflächenbefestigungsklemme
Stop letting your workpieces slip mid-cut. HONGDUI's SC-14 sets the workshop standard for dead-accurate, rock-solid surface clamping. Precision-machined for 20mm bench dog setups, every component is engineered for zero-tolerance stability. Whether you are executing aggressive hand planing or high-vibration routing, the SC-14 delivers an absolute, flex-free grip—ensuring your wood stays exactly where you want it, period.
Schnelle Exzenter-Spannung: Nutzt einen leichtgängigen, seitlich betätigten Exzenterhebel, um sofortigen Druck auszuüben, was schnelle Werkstückwechsel und effiziente Arbeitsabläufe ermöglicht.
Niedrigprofil-Design: Konstruiert, um außergewöhnlich flach auf der Werkbank zu liegen. Dies ermöglicht ungestörte Oberflächenarbeiten wie Schleifen, Fräsen oder Handhobeln über der Klemme.
Universelle Kompatibilität mit Bankhakenlöchern: Entwickelt für Standard-20-mm-Bankhakenlöcher (üblich in MFT-Systemen). Kann je nach spezifischer Pfostenkonfiguration auch für 19-mm- (3/4") Löcher angepasst werden.
Horizontale Druckausübung: Im Gegensatz zu herkömmlichen Vertikalklemmen übt die SC-14 seitlichen Druck aus und verkeilt das Werkstück sicher gegen einen Anschlag oder eine andere Klemme.
Einstellbarer Spannbereich: Der Gleitmechanismus ermöglicht eine Feinjustierung der Klemmenposition, um verschiedene Werkstückbreiten und unregelmäßige Formen aufzunehmen.
Schonende Kontaktfläche: Die Spannfläche ist so konzipiert, dass der Druck gleichmäßig verteilt wird, wodurch ein fester Halt gewährleistet wird, ohne die Kanten Ihres Holzes zu verbeulen oder zu beschädigen.
360-Grad-Rotation: Einmal in ein Bankhakenloch eingesetzt, kann die Klemme frei rotieren, um Druck aus jedem Winkel auszuüben, wodurch sie ideal für gekrümmte oder komplexe Werkstücke ist.

FAQ
Check out the most common questions our customers asked.
What is the main purpose of the SC-14 Fixing Clamp?
The SC-14 is a "pistol-grip" style quick clamp specifically engineered for woodworking workstations. Its primary role is to secure workpieces to a table or to lock guide rails (like those from Festool, Makita) into place for precise cutting and routing.
Which T-tracks is the SC-14 compatible with?
The clamp is designed to fit standard 12mm x 8mm T-track slots found on the underside of most professional guide rails. It also fits standard 19mm (3/4 Inch) T-tracks commonly used in homemade workbench tops and drill press fences.
Can I use these with an MFT (20mm hole) table?
Yes. While the clamp has a T-bolt head, it is frequently used in conjunction with 20mm bench dogs or specialized MFT adapters. It can be inserted from underneath the table through a 20mm hole to pull a workpiece tight against the table surface.
What is the maximum clamping capacity?
The SC-14 typically offers a clamping range of up to 160mm to 200mm (approx. 6–8 inches) depending on the specific rail length. This makes it ideal for everything from thin veneers to thick 8/4 hardwood slabs.
How does the "Quick-Release" mechanism work?
The SC-14 utilizes a trigger-action lever. You can slide the clamping jaw freely along the rail to close the gap quickly, then pump the trigger to apply final pressure. A dedicated release button allows the jaw to slide open instantly with one hand.
What is the clamping force of the SC-14?
Despite its lightweight feel, the mechanical ratcheting system can generate approximately 60kg to 100kg (130–220 lbs) of pressure. This is optimized for holding workpieces steady without the risk of crushing delicate wood fibers.
Are the clamping pads non-marring?
Yes. The SC-14 comes with removable soft plastic/rubber pads on both the fixed and moving jaws. These ensure that high clamping pressure does not leave indentations or "bruises" on finished wood surfaces.
What material is the clamp made of?
The main bar is made of hardened alloy steel to prevent bending under pressure, while the handle and trigger assembly are made of high-impact reinforced nylon and aluminum for a lightweight, ergonomic grip.
How do I maintain the ratcheting mechanism?
Keep the steel bar clean of resin, glue, and sawdust. If the trigger starts to slip, wipe the bar with a bit of denatured alcohol to remove oils. Avoid using heavy grease on the bar; a dry PTFE spray can be used on the internal trigger pivot if it becomes stiff.
Why is the clamp slipping on the bar?
This is usually caused by sawdust or wood pitch (resin) buildup on the steel bar. Clean the bar thoroughly. The ratcheting mechanism relies on friction against the bar; if the bar is too "polished" or oily, the teeth cannot grip.
Can I reverse the jaws to use it as a spreader?
Unlike some generic quick-clamps, the SC-14 is primarily designed for clamping. While some versions allow for the head to be moved to the opposite end, its main engineering focus is as a "pull-down" or "fixing" clamp for guide rails and tables.
