Overview

The Vimar VM07937 is a 35 mm fixing screw used to secure a mounting frame onto a rectangular mounting box. It uses a cross-slotted head so it can be tightened with a common Phillips screwdriver, which helps when you are working inside a helm panel, a distribution box, or a compact electrical enclosure.

On a boat, this kind of small hardware matters when you are reworking switches, outlets, and control panels and need the frame to sit square to the box after everything is wired and dressed. Confirm that your frame and rectangular box are the type that use frame-fixing screws and that a 35 mm length will not foul wiring or device bodies behind the panel.

Key features

• 35 mm length for fixing mounting frames on rectangular mounting boxes
• Cross-slotted head for installation with standard Phillips screwdrivers
• Useful replacement when original frame screws are missing after rewiring or refits
• Supports clean frame alignment in panels and enclosures when tightened to a snug fit
• Compact spare to keep in an onboard electrical kit for quick service work

Installation and fit

Start the screw by hand so it threads smoothly into the box insert, then tighten until the frame is firmly seated and aligned. Stop once the frame is secure, since over-tightening can distort plastic frames or damage threads in the mounting box.

Before final tightening, check clearance behind the panel. A 35 mm screw is typically used where shorter screws do not fully engage, but you still want to avoid contacting wiring bundles or the back of installed devices.

Use on board

This screw fits the kind of work that comes up during helm upgrades, cabin refits, or service on control units where rectangular mounting boxes are used. It is a good match for boat owners who handle their own panel work and for yards that keep spares on hand for ongoing electrical maintenance.

Maintenance and care

In damp lockers or exposed console areas, include fasteners in routine inspections and re-tighten only if needed. If a screw shows corrosion or seizing, replace it rather than forcing it, especially when it threads into embedded inserts.
