Clamping screw M18 x 2 L 20 mm for 25 mm collet chuck — TECWERK

A Clamping screw M18 x 2 L 20 mm designed for use with Ø 25 mm collet chucks, suitable for clamping tools with cylindrical shanks featuring a lateral drive surface to DIN 1835-B.

• M18 x 2 thread for standardised fit
• Compact 20 mm overall length
• Compatible with Ø 25 mm collet chucks
• Conforms to DIN 1835-B drive geometry

Precise interfacing with standard collet systems

The clamping screw provides a standardised M18 x 2 connection and a short, defined 20 mm overall length that supports reproducible seating in collet-based holders. By matching the nominal thread and the specified dimensions, the component minimises axial play and ensures repeatable positioning when used with Ø 25 mm collet chucks. This leads to reliable concentricity during spindle rotation and reduces the need for frequent re-centring, which is particularly valuable in batch production and high-precision workshop settings.

Secure torque transfer and reliable tool retention

Designed for tools with a cylindrical shank and a lateral drive surface to DIN 1835-B, the screw facilitates positive torque transmission between chuck and tool; the lateral drive surface prevents slippage under cutting loads. When installed correctly in a compatible chuck, the part supports consistent clamping force and reduces the risk of tool runout. This mechanical clarity simplifies setup procedures and contributes to predictable machining outcomes, improving process stability on the shop floor.

Streamlined integration and lower downtime

With a compact profile and standard thread form, the component fits established clamping workflows without custom adaptation. Parts exchange is straightforward, which shortens maintenance intervals and keeps spindle idle time to a minimum — a clear efficiency advantage for production environments. Combined with Metav’s logistics and supply reliability, procurement and replenishment become a predictable part of workshop planning, supporting continuous operation and straightforward stock management.

Application scope and practical considerations

The screw is intended for use with face-style clamping chucks and for securing tools that comply with the DIN 1835-B shank specification; it is therefore well suited to general-purpose turning and milling tool clamping where a lateral drive surface is present. As material information is not specified in the available data, verification against the chuck manufacturer’s recommendations is advised when specific material or heat-treatment properties are required. Where interchangeability with existing tooling is a concern, refer to chuck diameter and drive-surface compatibility first to confirm fit.

FAQ

Is this screw compatible with collet chucks other than 25 mm?
Compatibility is determined by the chuck’s specified clamping diameter; this clamping screw is intended for use with collet chucks of Ø 25 mm and may not seat correctly in other sizes.

What does DIN 1835-B mean for tool shanks?
DIN 1835-B specifies a cylindrical shank with a lateral drive surface; the clamping screw and matching chuck transmit torque via that drive surface to prevent slippage during machining.

Can the screw be used with any face clamping chuck?
The screw is designed for face clamping chucks that accept an M18 x 2 fixing and a 25 mm clamping interface; verification against the chuck manufacturer’s specifications is recommended.

How many items are supplied per packaging unit?
The packaging unit is 1, so each shipment contains a single clamping screw.

Is special installation tooling required?
No special tooling is listed for basic installation; standard tightening procedures for screws with an M18 x 2 thread are applicable, though adherence to the chuck supplier’s assembly instructions is advised.
