Elesa+Ganter BT.32-SST-P-M8X40-SV21 Fluted Knob
The Elesa+Ganter BT.32-SST-P-M8X40-SV21 fluted knob is a practical industrial component for manual locking, tightening, and positioning tasks where durability and controlled contact matter. Although knobs are often treated as simple accessories, the right specification can improve daily usability, reduce wear on machine parts, and support more reliable adjustment in demanding environments.
This version belongs to the BT-SST-p-SV family and uses a black polyamide-based technopolymer knob body, an AISI 303 stainless steel threaded stud, and a technopolymer locking thrust pad. The material combination is well suited to industrial settings where corrosion resistance, repeatable handling, and long-term service reliability are all important considerations.
Dimensions and Material Profile
The Elesa+Ganter BT.32-SST-P-M8X40-SV21 fluted knob has a 32 mm diameter and an M8 threaded stud with 40 mm length. This makes it a versatile mid-length option for machinery and equipment where deeper engagement than 30 mm is needed, but where the longest stud versions are unnecessary. The SV21 thrust pad adds another important design detail by helping create a more controlled contact point during tightening.
The fluted shape improves grip during manual operation, which is important in maintenance, adjustment, and repetitive clamping tasks. The stainless steel stud also strengthens its suitability for machine assemblies installed in humid, cleaning-sensitive, or corrosion-aware environments.
Application Value in Industrial Equipment
This fluted knob can be used in packaging systems, support brackets, access covers, adjustable guide rails, enclosure panels, and machine fixtures. The 40 mm stud length gives it a balanced profile for general industrial use. It is long enough for many mounting situations without becoming unnecessarily extended in compact installations.
One of the strongest functional advantages of the Elesa+Ganter BT.32-SST-P-M8X40-SV21 fluted knob is its locking thrust pad. Instead of transferring force directly from the threaded stud to the target surface, the design helps protect the clamped part. In practical use, this can support cleaner repeated operation and help preserve surfaces over time.
Why This Version Is a Strong General-Purpose Choice
Among similar hand knobs, this version sits in a very useful middle position. It combines the grip and handling benefits of the 32 mm BT knob format with a corrosion-resistant M8 stainless stud and a moderate 40 mm thread length. The SV21 pad format can also be attractive in assemblies where a broader contact configuration is desirable.

Elesa+Ganter BT.32-SST-P-M8X40-SV21 FAQ
What is the Elesa+Ganter BT.32-SST-P-M8X40-SV21 fluted knob mainly used for?
It is mainly used for manual clamping and adjustment in machinery, fixtures, and industrial equipment. Common applications include access panels, positioning systems, support structures, and adjustable machine elements.
Why choose the SV21 version instead of SV18?
The SV21 version uses a different thrust pad size, which changes the contact characteristics of the locking point. Depending on the surface and assembly layout, that may provide a more suitable clamping interface.
Is the stainless steel stud important for industrial environments?
Yes. AISI 303 stainless steel improves corrosion resistance and makes the knob better suited to moisture-prone or washdown-conscious applications than comparable parts with standard steel studs.
Is 40 mm a versatile stud length?
Yes. A 40 mm stud is often a practical all-round choice because it provides more reach than short versions while remaining manageable in many standard machine layouts.
Can this knob help protect the surface being clamped?
Yes. The locking thrust pad is specifically intended to reduce direct stud contact with the target surface, helping lower the risk of marks, indentation, or surface wear during repeated tightening.
