Elesa+Ganter BT.40-SST-P-M10X55-SV21 Fluted Knob

The Elesa+Ganter BT.40-SST-P-M10X55-SV21 fluted knob is built for manual tightening tasks where a longer threaded stud and a protected contact point are both important. As part of the BT-SST-P series, this model pairs a black technopolymer knob with an AISI 303 stainless steel stud and a POM locking thrust pad. That combination is useful in industrial systems where the operator needs reliable hand control and the assembly needs a more careful clamping interface.

Designed for Longer Reach

One of the defining characteristics of the Elesa+Ganter BT.40-SST-P-M10X55-SV21 fluted knob is its 55 mm M10 stud. That added length can make installation easier in deeper mounting points, enclosed machine sections, or assemblies where the clamping point sits beyond a panel, bracket, or cover. The knob remains easy to grip thanks to its 40 mm diameter and fluted profile.

Practical Application Areas

This model is well suited for machine guarding, adjustable housings, stainless-compatible assemblies, process equipment, and industrial fixtures that need hand-operated locking. The locking thrust pad helps distribute contact more intelligently and can be valuable wherever the clamped surface should stay cleaner and less damaged over time.

Why This Configuration Matters

Not every clamping knob needs an extended stud, but when the design does, it helps to use a part that still feels manageable in the hand. The Elesa+Ganter BT.40-SST-P-M10X55-SV21 fluted knob does that well. It offers the extra engagement length needed for some equipment layouts while keeping the handling familiar and controlled. That makes it relevant for engineers, maintenance teams, and machine builders looking for dependable manual adjustment hardware.

Elesa+Ganter BT.40-SST-P-M10X55-SV21  FAQ

What is the main benefit of the 55 mm stud length?

The 55 mm threaded stud helps when the fastening point is recessed or when the knob must pass through a panel, bracket, or structural section before clamping the target component.

Why choose the Elesa+Ganter BT.40-SST-P-M10X55-SV21 fluted knob instead of a shorter version?

This version is better when the application demands more reach or deeper thread engagement. It can simplify installation in equipment layouts where space or mounting depth makes shorter studs less practical.

Does the locking thrust pad protect surfaces?

Yes. Its purpose is to reduce direct contact between the threaded stud and the clamped surface, which can help limit wear, marking, or concentrated pressure.

Is this suitable for environments that require stainless hardware?

The stud is made from AISI 303 stainless steel, so it is a strong option for environments where corrosion resistance is a material requirement or a preferred design feature.

Is the knob comfortable for manual use?

Yes. The fluted shape improves grip during hand tightening, and the 40 mm diameter gives a practical feel for repeated adjustments during setup or maintenance.

Can this knob be used in machine building?

Absolutely. It fits well in machine building, industrial enclosures, line equipment, and adjustable mechanisms where manual locking is needed without switching to a tool-driven fastener.
