Elesa+Ganter B.193/15-SST-M4 Knurled Grip Knob

The Elesa+Ganter B.193/15-SST-M4 knurled grip knob is a compact industrial knob engineered for reliable hand tightening in mechanical, electrical, and equipment-building applications. While small in size, it plays an important role in everyday machine usability. Operators, technicians, and maintenance teams often depend on components like this to make quick, accurate adjustments without interrupting workflow.

Overview of the Product

This model is part of the B.193 family of knurled grip knobs and features a black phenolic based duroplast body with an AISI 303 stainless steel threaded blind hole. The M4 connection size gives it broader application flexibility than smaller thread formats while still preserving a compact footprint. It is well suited to assemblies where hand access, repeatable tightening, and corrosion-conscious design are all priorities.

Technical Specifications

The Elesa+Ganter B.193/15-SST-M4 knurled grip knob has a knob diameter of 15 mm and an overall length of 11 mm. It uses an M4 blind threaded insert in AISI 303 stainless steel. The body is made from phenolic based PF duroplast in black with a glossy finish. The published operating temperature range is -20°C to +110°C, which supports use in a wide range of industrial conditions.

Elesa+Ganter B.193/15-SST-M4 Practical Applications in Industry

An M4 knurled hand knob is often chosen for light-to-medium manual fastening points, including inspection covers, guide settings, panel retention points, machine guards, compact enclosures, and adjustment assemblies. The advantage of this size is versatility. It offers more thread engagement potential than M3 while remaining suitable for compact machine design.

Because the grip surface is knurled, users can apply controlled hand force more confidently. That matters in environments where operators need a consistent grip even during repetitive tasks. The design helps reduce slippage and supports better handling when fast adjustments are required.

Elesa+Ganter B.193/15-SST-M4 Material and Performance Benefits

Material selection is one of the most important parts of choosing the right machine knob. In this version, the phenolic duroplast body contributes rigidity, stable geometry, and a durable external finish. These qualities make it appropriate for industrial interfaces that experience frequent contact.

The stainless steel insert adds another layer of functional value. In applications with humidity, cleaning routines, or variable environmental exposure, an AISI 303 stainless steel boss can be a better long-term specification than a standard plated option. This makes the product a practical fit for machinery builders, OEM projects, and maintenance teams looking for dependable component behavior over time.

How to Choose the Right Variant

If you are selecting between M3, M4, and M5 knob versions, M4 often sits in the middle as a balanced solution. It is compact enough for tight spaces but robust enough for a broad range of manual adjustment points. The Elesa+Ganter B.193/15-SST-M4 knurled grip knob is therefore a strong option for designers searching for a stainless steel threaded knob, industrial adjustment knob, or knurled grip knob for technical assemblies.

Elesa+Ganter B.193/15-SST-M4 FAQ

What is the advantage of the M4 thread on this knob?

The M4 thread offers a useful balance between compact design and practical fastening capability. It is often selected when M3 feels too small but a larger knob would take up unnecessary space in the assembly.

Is the insert fully stainless steel?

Yes. This version is specified with an AISI 303 stainless steel threaded blind hole, which improves corrosion resistance and supports use in more demanding industrial environments.

What kind of machines can use this knob?

It can be used on packaging equipment, light industrial machinery, electronic housings, access covers, instrumentation frames, and adjustment systems where manual tightening is part of normal operation.

Does the glossy black finish have only a visual role?

No. While appearance matters, the finish also reflects the durable nature of phenolic duroplast. The result is a professional-looking control component that maintains its shape and feel under repeated handling.

Can this knob be used where frequent cleaning is required?

In many cases, yes. The stainless steel insert helps in environments where resistance to oxidation is important. Final suitability still depends on the full chemical and operating conditions of the installation.

Why do engineers choose knurled knobs instead of plain knobs?

Knurled knobs improve finger grip, which leads to better handling and more controlled manual torque. That is especially valuable when adjustments are made often or when precision matters during setup.
