Elesa+Ganter BT.20-SST-P-M6X25

Elesa+Ganter BT.20-SST-P-M6X25 Fluted Knob Overview

The Elesa+Ganter BT.20-SST-P-M6X25 fluted knob is a manual clamping element developed for assemblies that need a compact knob body and a slightly longer threaded reach than shorter M6 stud versions. It combines a black technopolymer grip with an AISI 303 stainless steel stud, giving engineers a component that supports repeatable handling and improved resistance to corrosion in professional machine environments.

Product Configuration and Build

Within the BT family, this model belongs to the BT-SST-p execution. That means the knob body is made from polyamide-based technopolymer with a matte black finish, while the threaded stud is stainless steel and formed with a chamfered flat end according to UNI 947 / ISO 4753. The official dimensional line for this code identifies a 20 mm knob diameter, M6 thread, 15 mm overall knob height, 11.5 mm upper diameter, 11 mm lower diameter, 25 mm stud length, and a 6 mm reference with a final 9 mm value shown in the series table.

When a 25 mm Stud Length Makes Sense

The key reason to specify the Elesa+Ganter BT.20-SST-P-M6X25 fluted knob is thread reach. A 25 mm stud can be useful when the knob must pass through thicker machine walls, mounting plates, covers, or bracket stacks before achieving secure engagement. Compared with a 20 mm version, it gives more flexibility where tolerances, washers, slots, or layered assemblies increase the effective grip distance.

That does not make it oversized. The 20 mm knob diameter still keeps the overall component compact, which is helpful in dense machine layouts where adjacent parts, safety covers, or operator access zones leave limited space.

Common Engineering Uses

This knob is often relevant for instrumentation panels, adjustment slides, light clamping stations, enclosure access points, and process equipment that benefits from hand-operated fastening. Because the stud is stainless steel, the model is also well aligned with applications where moisture, regular washdown, or general corrosion concerns influence hardware selection.

Elesa+Ganter BT.20-SST-P-M6X25  FAQ

What is the main difference between BT.20-SST-P-M6X20 and BT.20-SST-P-M6X25?

The most important difference is the threaded stud length. This model uses a 25 mm M6 stud, which gives extra reach for thicker panels or deeper engagement. The knob diameter and core material concept stay within the same BT.20 family.

Is the stainless steel stud important in real applications?

Yes. In many industrial settings, the stud is the part most exposed to moisture and process conditions. AISI 303 stainless steel can help improve durability and maintain a cleaner appearance over time compared with ordinary plated steel alternatives.

Does a 20 mm knob provide enough grip for daily use?

For many medium-duty manual adjustments, yes. The fluted profile improves control and finger contact, which helps users tighten or loosen the knob more confidently than a smooth round design of similar size.

Where is this knob typically installed?

It is commonly used on machine covers, positioning fixtures, sensor brackets, access panels, modular jigs, and compact industrial devices where manual adjustment is part of routine maintenance or setup.

Should this knob be chosen for high torque tightening?

It is generally intended for manual clamping and repeated adjustment rather than extreme tightening loads. If an application demands very high torque, engineers usually evaluate larger knob diameters, lever systems, or tool-operated fastening solutions.
