Clamping lever M8x30 – adjustable handle, dark grey RAL 7021, for 30-, 40- and 45-series profiles

The clamping lever M8x30, also referred to as an adjustable handle M8x30, is a practical component designed for quickly tightening, loosening and locking adjustable parts of a structure. The lever has an external M8 threaded stud with a length of 30 mm and can be used in structures made from 30-, 40- and 45-series aluminium profiles.

The handle body is manufactured from plastic in dark grey RAL 7021, while the mechanism components are made from steel. The adjustable handle allows the connection to be operated manually without having to use an Allen key each time.

Instead of tightening a standard screw with a tool, the user rotates the lever. This solution makes it easier to adjust brackets, plates, supports, guides, stops, mounting brackets and other components used in modular technical structures.

Adjustable handle M8x30 for quick adjustment

The adjustable handle M8x30 is suitable for locations where a connection is regularly tightened, loosened or repositioned. It can be used in adjustable structural parts where the use of a standard socket head screw would require an additional tool each time.

Rotating the handle tightens or loosens the M8 threaded stud. This makes it possible to release the mounting more quickly, change the position of the adjustable component and then lock it again in the selected position.

The lever can be used, among other applications, at workstations and assembly stations, in machine frames, brackets, guides, stops and other structures requiring periodic adjustment.

Adjustable mechanism with 12 teeth

The handle mechanism has 12 teeth and allows the position of the lever to be changed without further tightening or loosening the threaded stud. After the handle is pressed, it can be rotated freely and positioned in a convenient direction.

The repositioning function is particularly practical in confined spaces where the handle could interfere with an aluminium profile, plate, guard, guide or another structural component.

After tightening, the lever can be positioned so that it remains easily accessible, does not protrude in an unwanted direction and does not interfere with workstation operation. The adjustable mechanism also makes it easier to install several handles close together.

Dark grey RAL 7021 plastic body

The handle body is manufactured from plastic. The material provides a lightweight and functional construction suitable for manually tightening and loosening adjustable connections.

The body colour is dark grey RAL 7021. The technical finish complements both silver-grey and black aluminium profiles, as well as other components used in industrial, assembly and workshop workstations.

The components working with the handle mechanism are manufactured from steel. The combination of a plastic body and steel components provides a practical solution for operating adjustable connections in modular structures.

External M8 thread with a length of 30 mm

The lever has an external M8 thread with a length of 30 mm. The longer stud allows the handle to be used in connections involving brackets, plates, mounting brackets, guides, stops, spacer sleeves and other adjustable structural parts.

Before installation, check the total thickness of the mounted components, the available thread depth and the position of the mating part. The stud length should be matched to the specific mounting configuration.

The stud should not reach the bottom of the hole before sufficient clamping pressure has been applied to the mounted component. It is also necessary to ensure that the thread engagement length is sufficient to secure the adjustable structural part firmly.

Dimensions of the M8x30 clamping lever

The following values correspond to the designations used in the technical drawing of the product:

• A1 – handle length: 74 mm,
• H3 – handle height: 41.9 mm,
• L – thread length: 30 mm,
• X – thread: M8,
• A: 64.5 mm,
• B: 17.5 mm,
• D: 13.5 mm,
• D1: 17 mm,
• D2: 19 mm,
• H: 28 mm,
• H1: 5.5 mm,
• H2: 14 mm,
• H4: 38 mm,
• number of teeth: 12.

Compatibility with 30-, 40- and 45-series aluminium profiles

The M8x30 clamping lever can be used in structures made from structural aluminium profiles from the following series:

• 30-series aluminium profiles: 8 mm T-slot,
• 40-series aluminium profiles: 8 mm T-slot,
• 45-series aluminium profiles: 10 mm T-slot.

When mounting the lever directly in the profile slot, use an M8 T-slot nut or slot nut matched to the slot geometry of the relevant series. One version of the T-slot nut may not be compatible with all the listed profile systems.

The lever can also be screwed into other components with a correctly prepared M8 thread, such as brackets, mounting plates, blocks, connectors, mounting brackets and adjustable structural parts.

Installing the M8x30 clamping lever

• Checking the mounting point: make sure that the mating component has a correctly prepared M8 thread.
• Selecting the T-slot nut: when mounting in the profile slot, use an M8 T-slot nut or M8 nut suitable for series 30, 40 or 45.
• Checking the stud length: make sure that the 30 mm thread length is suitable for the thickness of the mounted parts and the available connection depth.
• Positioning the components: place the adjustable bracket, plate, guide or another component in the required position.
• Screwing in the stud: insert the M8 thread into the mating component and rotate the handle until sufficient clamping pressure is achieved.
• Repositioning the handle: if necessary, press the handle and rotate it to a position in which it does not interfere with the structure.
• Checking the mounting: check that the adjustable component is stable and does not change position during use.
• Loosening: rotate the handle in the opposite direction to release the connection and reposition the mounted component.

The tightening force should be matched to the type of mounted component, the structural material and the strength of the thread used. The product data does not specify a maximum tightening torque.

Practical lever for adjustable aluminium profile structures

The clamping lever M8x30 is a functional component for quickly locking and adjusting structural parts without having to use an Allen key each time. The external M8 threaded stud with a length of 30 mm allows the handle to be used in connections involving thicker plates, mounting brackets, spacer sleeves and other components matched to the thread length.

The dark grey RAL 7021 plastic body, steel components, 12-tooth mechanism and adjustable handle position make the product a practical addition to workstations, machine frames, brackets, guides and other adjustable technical structures made from 30-, 40- and 45-series aluminium profiles.
