Elesa+Ganter 108821 BT.40-SST-P-M10X35-SV32 Fluted Clamping Knob
The Elesa+Ganter 108821 fluted clamping knob is designed for secure manual tightening in assemblies where clean operation, reliable grip and corrosion resistance matter. This version, identified as BT.40-SST-P-M10X35-SV32, combines a black polyamide-based technopolymer knob with an AISI 303 stainless steel threaded stud and a technopolymer locking thrust pad. The result is a practical component for fixture systems, machine guards, equipment covers and adjustable mechanical parts that need repeatable clamping without damaging the contact surface.
Technical Features of Elesa+Ganter 108821
This model belongs to the BT-SST-p-SV family of fluted knobs with locking thrust pad. It features a 40 mm knob diameter, an M10 threaded stud and a 35 mm stud length. The SV32 thrust pad helps distribute contact force while reducing direct stud-to-surface contact. That detail is especially useful when the clamped component must stay protected from marks, dents or concentrated pressure during repeated adjustment.
Material and Performance Benefits
The body is made from durable PA technopolymer with a matte black finish, giving the knob a solid feel and dependable grip in manual handling applications. The stainless steel threaded stud supports use in environments where resistance to moisture and general corrosion is important. In production spaces, maintenance zones and technical installations, this material combination supports long service life with low upkeep. The POM thrust pad also contributes to smoother locking action and helps preserve the mating surface over time.
Where the 108821 Fluted Clamping Knob Is Used
The Elesa+Ganter 108821 BT.40-SST-P-M10X35-SV32 fluted clamping knob is a strong fit for industrial equipment, packaging machinery, inspection devices, processing units and custom-built frames. Because it is manually operated, it is ideal in applications where operators need quick locking and loosening without additional tools. The 35 mm stud length is often preferred where installation depth is moderate and compact positioning is required.

FAQ
What makes the Elesa+Ganter 108821 different from a standard clamping knob?
This model includes a locking thrust pad, which helps protect the contact surface during tightening. In many assemblies, that is an advantage over basic knobs that apply pressure directly through the threaded end.
Is the 108821 suitable for environments where corrosion resistance is important?
Yes. The threaded stud is made from AISI 303 stainless steel, making it a practical option for installations where exposure to humidity, washdown routines or general corrosive conditions is a concern.
Why would someone choose the M10x35 version?
The M10x35 format offers a useful balance between holding strength and compact installation. It works well when the assembly needs secure tightening but the available thread depth or mounting space is limited.
Can this knob help prevent surface damage on the clamped part?
Yes. The integrated thrust pad is specifically intended to reduce direct contact between the stud and the clamped surface. That can be valuable for coated, machined or finished parts that should remain in good condition after repeated adjustment.
