Elsa+Ganter 102121 Knurled Knob: B.193/15-SST-P-M4X6 Details
The Elsa+Ganter 102121 knurled knob, or B.193/15-SST-P-M4X6, is a compact hand-fastening component built for applications that need the stronger thread profile of M4 in a very short stud length. This makes it especially interesting for designers who want a secure hand-operated interface without excessive thread projection behind the mounting surface.
Key Identity of the B.193/15-SST-P-M4X6
This model uses a 15 mm knob diameter, an M4 stainless steel threaded stud, and a 6 mm stud length. In practice, that means it can suit compact covers, access panels, guide plates, and adjustment points where the available thread depth is limited. It is often better to choose a shorter stud intentionally than to use a longer one that bottoms out or interferes with nearby internal components.
The knurled geometry supports easy finger grip, helping operators tighten the knob quickly during setup or servicing. That simple usability advantage becomes more important in machines and devices that are opened repeatedly.

Elesa+Ganter 102121 Why M4 Can Be the Better Choice
Compared with M3 variants, an M4 thread can provide a more robust fastening interface in many light-to-medium duty applications. It may offer more confidence where a compact knob still needs to feel mechanically secure. At the same time, the 6 mm stud length keeps the component suitable for shallow mounting zones.
This balance is useful in technical enclosures, precision devices, compact assemblies, and machine elements where internal clearance matters. Engineers often look for exactly this kind of combination: stronger thread size, controlled stud length, and consistent hand operation.
Use Cases and Practical Relevance
The Elesa+Ganter 102121 knurled knob fits equipment where space is tight and clean manual adjustment is preferred over tools. Typical areas include instrumentation housings, removable covers, small fixtures, electronic enclosures, guarding systems, and compact automation components. Its short stud length can help avoid interference with internal parts, wiring, or moving mechanisms.

Elesa+Ganter 102121 Elesa+Ganter 102121 FAQ
Why choose M4x6 instead of M3x10?
An M4x6 knob gives a different balance. It offers a thicker thread with a shorter projection. That can be preferable when the receiving thread is shallow or when designers want more thread diameter without extra stud length.
Is a 6 mm stud too short for practical use?
Not necessarily. It is ideal in assemblies designed around shallow engagement. In many compact technical products, a short stud is actually the safer and more appropriate choice because it avoids bottoming out or extending into sensitive areas.
What kind of grip does the knob provide?
The knurled outer profile improves traction during hand tightening. This is useful in maintenance or adjustment tasks where a user needs a reliable touch point without using additional tools.
Does the stainless steel stud improve service life?
In many environments, yes. Stainless steel helps reduce rust-related deterioration and supports more stable long-term performance where humidity or regular cleaning is part of normal operation.
Where is this knob typically installed?
It is often relevant for compact industrial and technical assemblies such as machine covers, calibration points, control housings, protective guards, and small access interfaces that require repeatable hand fastening.
