Elesa+Ganter BT.32-SST-P-M8X30-SV21 Fluted Knob
The Elesa+Ganter BT.32-SST-P-M8X30-SV21 fluted knob is a compact manual clamping solution for equipment that needs dependable hand tightening and controlled surface protection. In industrial design, a knob may look like a small detail, but it often plays a major role in usability, maintenance speed, and component longevity. This model is built for precisely that kind of functional performance.
It combines a matte black polyamide-based technopolymer knob body with an AISI 303 stainless steel threaded stud and a technopolymer locking thrust pad. That combination supports both handling comfort and reliable use in environments where corrosion resistance matters. It is especially relevant in machines, fixtures, and adjustment systems that are tightened and released on a regular basis.
Technical Characteristics
The Elesa+Ganter BT.32-SST-P-M8X30-SV21 fluted knob features a 32 mm knob diameter, an M8 threaded stud, and a 30 mm stud length. Compared with longer versions, this shorter stud makes the component a good choice for compact layouts, shallow mounting points, and applications where excess thread length would add no value. The SV21 version also includes a larger thrust pad than the SV18 configuration, which can be useful when a slightly broader contact profile is preferred.
The fluted external shape supports solid grip during manual adjustment, while the thrust pad helps avoid direct stud contact with the mating surface. In practical engineering terms, that means reduced surface marking and improved suitability for repeated clamping tasks.
Typical Uses in Industry
This product can be used in machine guards, operator panels, instrumentation supports, laboratory equipment, packaging machinery, and precision adjustment points. The compact M8x30 configuration is especially useful in tighter assemblies where longer studs could interfere with nearby components or create unnecessary protrusion.
Because the stud is stainless steel, the Elesa+Ganter BT.32-SST-P-M8X30-SV21 fluted knob also fits applications where better resistance to oxidation or routine washdown conditions is required. That makes it a practical option for many modern machine builds, particularly where both durability and clean design are valued.
Why Engineers Choose This Variant
Engineers often choose this version when they want the BT series grip profile and stainless steel threaded stud, but in a shorter format that suits compact equipment. The SV21 pad size can also help distribute contact more effectively depending on the locked surface and assembly geometry. This makes the part well suited to applications where both space efficiency and controlled clamping matter.

FAQ
What makes the Elesa+Ganter BT.32-SST-P-M8X30-SV21 fluted knob different from other BT models?
This version combines a 32 mm knob diameter with an M8 stainless steel stud, a 30 mm stud length, and the SV21 thrust pad format. That specific mix makes it useful for compact installations that still need dependable manual clamping.
Why would I choose a 30 mm stud instead of a 40 mm or 50 mm version?
A 30 mm stud is often the better choice when the mounting point is shallow or when a longer stud would interfere with nearby machine parts. It helps keep the assembly more compact and controlled.
What is the benefit of the SV21 thrust pad?
The SV21 thrust pad provides controlled contact between the knob assembly and the clamped surface. It helps reduce direct stud pressure and can improve how the load is applied in repeated locking operations.
Can this knob be used in corrosion-sensitive environments?
Yes. The AISI 303 stainless steel stud improves corrosion resistance, which is valuable in industrial environments exposed to humidity, cleaning agents, or general moisture.
Is this a good option for frequent manual adjustment?
Yes. The fluted grip shape is designed for repeated hand operation, making this knob well suited to adjustment points that are accessed during setup, maintenance, or routine equipment changes.
