Understanding the Elesa+Ganter BT.32-SST-P-M8X50-SV25 Fluted Knob
The Elesa+Ganter BT.32-SST-P-M8X50-SV25 fluted knob is designed for manual clamping and positioning tasks that need a longer threaded reach without giving up surface protection. It belongs to the BT-SST-p-SV family, a line that combines a PA technopolymer knob, an AISI 303 stainless steel stud, and a POM technopolymer thrust pad. The result is a hand-operated component that supports repeated tightening while reducing direct pressure from the stud onto the clamped surface. The manufacturer’s table lists this model as code 108725 and confirms that it uses a 50 mm long M8 threaded stud.
Technical Specifications
For this exact version, the documented dimensions are D = 32 mm, thread = M8, L = 22 mm, d1 = 17 mm, d2 = 21 mm, d3 = 25 mm, d4 = 6 mm, l1 = 50 mm, l2 = 9 mm, l3 = 5.5 mm, l4 = 10.5 mm, and l5 = 6 mm. These measurements show that the Elesa+Ganter BT.32-SST-P-M8X50-SV25 fluted knob is the long-reach option among the SV25 M8x30, M8x40, and M8x50 variants. That longer threaded section can be useful in assemblies with deeper mounting zones, layered structures, or wider adjustment travel requirements.
Where the 50 mm Stud Length Helps
Longer studs are often selected when designers need to bridge thicker brackets, pass through multiple structural parts, or preserve a broader clamping range. In practical machinery, this can include adjustable fences, guarding systems, modular jigs, inspection fixtures, and operator-adjustable support mechanisms. The thrust pad is a particularly useful detail in these contexts because it helps prevent the stainless steel stud from bearing directly on the work surface.
Material Performance in Real Applications
The technopolymer knob body supports frequent handling while keeping the component relatively light. The AISI 303 stainless steel stud adds corrosion resistance for sectors that demand better material durability than standard plated steel may offer. The POM thrust pad contributes to smoother contact behavior at the clamping point. For more information, explore Elesa+Ganter.
Best-Fit Applications
This version is especially relevant where a short stud would limit installation flexibility. It is a practical choice for manual locking points in machine frames, adjustable process equipment, panel hardware, sliding guides, and maintenance-friendly mechanisms where operators need to tighten and release components regularly.
Elesa+Ganter BT.32-SST-P-M8X50-SV25 FAQ
Why choose the 50 mm version instead of the 30 mm or 40 mm models?
The longer stud gives more usable reach and can accommodate thicker assemblies or deeper engagement zones. It may also allow more flexibility in custom setups where the clamping point is recessed or where adjustment travel is greater.
Elesa+Ganter BT.32-SST-P-M8X50-SV25 Is this product mainly for manual tightening?
Yes. The fluted knob shape is intended for hand operation. It is well suited to manual adjustment points where fast, repeatable tightening is more important than high-torque tool-driven fastening.
Elesa+Ganter BT.32-SST-P-M8X50-SV25 What does the thrust pad really do in practice?
In practice, it acts as a buffer between the stud and the surface being clamped. That can help reduce scratches, point loading, and direct metal contact, especially in assemblies that are adjusted often or where the surface finish needs to stay intact.
Can this knob be used in hygienic or washdown environments?
The AISI 303 stainless steel stud improves corrosion resistance, but final suitability depends on the full system design and the actual cleaning regime. Engineers should evaluate the complete environmental requirements, including chemicals, moisture, temperature, and maintenance cycles.
What makes this model distinctive within the BT-SST-p-SV family?
Its distinctive point is the combination of a 32 mm knob, M8 thread, 50 mm stud length, and SV25 thrust pad dimensions. That balance makes it a practical option when users need a compact knob body with extended threaded reach.
