Elesa+Ganter B.193/30-SST-M8 Knurled Grip Knob Guide

The Elesa+Ganter B.193/30-SST-M8 knurled grip knob is designed for manual tightening tasks where durability, grip consistency, and corrosion resistance matter. This version combines a phenolic-based PF duroplast body with an AISI 303 stainless steel threaded blind hole, making it a practical option for industrial equipment, maintenance assemblies, and machine components that require repeatable hand adjustment.

Elesa+Ganter B.193/30-SST-M8 What Makes the B.193/30-SST-M8 Different?

This model belongs to the B.193 family of knurled grip knobs, a series known for compact geometry and dependable hand control. The 30-size version has an outside diameter of 31 mm, with an M8 threaded blind hole. The glossy black duroplast surface offers a classic industrial finish while also supporting a firm tactile feel during manual operation. Because the threaded insert is stainless steel, the knob is especially relevant in environments where moisture, cleaning routines, or light corrosion exposure are part of normal use.

Material and Technical Characteristics

The body is made from phenolic-based duroplast, a material appreciated for dimensional stability and a hard, rigid feel. In practical use, that means the knob maintains shape well during repeated tightening cycles. The stainless steel insert improves resistance to oxidation compared with standard plated alternatives. For engineers and buyers comparing hand knobs for machines, fixtures, housings, and access points, this balance of rigid polymer and stainless steel hardware is one of the main strengths of the product.

Typical Application Areas

The Elesa+Ganter 102501 knurled grip knob is suitable for guarding panels, machine covers, inspection access points, positioning elements, and general clamping tasks where hand tightening is preferred. It also fits installations that benefit from a more refined corrosion-resistant specification without switching to a fully metallic knob.

Why Size and Thread Matter

The M8 thread makes this knob a strong fit for medium-duty manual fastening points. The 31 mm diameter offers a comfortable finger grip without adding excessive bulk to compact assemblies. In many industrial layouts, that combination helps maintain accessibility while supporting reliable everyday use.

FAQ

Is the B.193/30-SST-M8 suitable for corrosive environments?

It is a strong choice for environments where corrosion resistance is important. The AISI 303 stainless steel insert performs better than standard plated metal in humid or lightly aggressive conditions, while the duroplast body remains stable and easy to handle.

Elesa+Ganter B.193/30-SST-M8 What kind of mounting does this version use?

This model uses a threaded blind hole, which means the mating fastener threads into the knob rather than extending through it. That makes it useful when a clean external appearance and controlled engagement depth are preferred.

Elesa+Ganter B.193/30-SST-M8 Where is this knob commonly used?

It is often used on machinery covers, adjustment points, access panels, maintenance closures, and assemblies that need frequent manual fastening and release.

Is this a good option for hygienic or washdown-adjacent areas?

It can be a practical option where better resistance to moisture and cleaning agents is required, although final suitability should always be checked against the actual chemical exposure, cleaning process, and regulatory expectations of the installation.
