Anzugsbolzen DIN2080 Ott-Ringnut SK40 with internal M16 thread (TECWERK)

A TECWERK pull stud designed to secure SK40 taper tool holders, complying with the DIN 2080 retention knob standard and intended for industrial clamping use.

• DIN 2080 retention knob standard
• Internal thread M16 for secure anchoring
• Compatible with SK40 taper holders
• Sealing ring included for secure fit

Secure clamping for consistent machining

The design follows the DIN 2080 specification to deliver repeatable retention forces for tool holders with an SK40 taper. By using a standardised retention knob, the system minimises runout variability and supports predictable tool behaviour during high-precision operations. The combination of standard compliance and precisely defined diameters contributes to reduced tool-change time and stable spindle engagement, which in turn supports steady production cycles and lower scrap rates.

Threaded connection that enhances safety and serviceability

An internal M16 thread provides a secure mechanical interface between the retention knob and the tool holder assembly. This internal threading simplifies installation and removal compared with external-thread variants, while the integrated sealing ring helps protect the connection from coolant ingress and swarf accumulation. The result is easier maintenance and longer service intervals for clamping components, translating into less unplanned downtime on the shop floor.

Clear dimensional data for correct selection

Critical dimensions such as d1, d2, d3 and length values are specified to ensure compatibility with matching tool holders and chucks. Precise diameters and length specifications mean that the component locates and seats exactly where intended, avoiding misfit or excessive play. This dimensional clarity supports engineers and buyers in verifying fitment against existing SK40 spindles and fixtures, reducing the risk of ordering incompatible parts.

Reliability through industry fit and material neutrality

Supplied to meet the DIN 2080 norm and labelled as an Ott-style ring nut, the component focuses on function and fit rather than decorative finishes. Where material choices and coatings are required in specific environments, selection should be based on documented requirements; the current specification prioritises conformity to retention standards and secure engagement. For customers seeking consistent clamping performance, this retention knob variant represents a pragmatic balance between standardised geometry and operational reliability.

FAQ

Is this retention knob compatible with standard SK40 tool holders?
Yes. The retention knob is designed to the DIN 2080 specification and is compatible with standard SK40 taper holders when the matching retention geometry is present.

What does the internal M16 thread mean for installation?
The M16 internal thread provides a secure, serviceable interface for installation and removal, reducing the chance of thread damage compared with some external-thread designs.

Does the product include a sealing ring to protect against coolant and swarf?
Yes. The Ott-ringnut variant specified includes a sealing ring to help protect the threaded connection from ingress and contamination during machining.

Where can the dimensional details be found for verification?
Dimensional values such as d1, d2, d3, L1 and L2 are published in the technical section above and can be used to verify fitment with existing SK40 tooling.
