SEBO M4 Nut, Steel (DIN 562) - 10 Pack

Where a screw has to clamp against a panel rather than into a tapped boss, SEBO puts a separate nut on the back of the joint. Part 0131ER covers that job ten at a time: steel nuts to DIN 562, the standard covering the thin, unchamfered square nut, sized to the M4 screws found throughout the machine. The square form is deliberate, because it drops into a moulded pocket in the housing and is held from turning while the screw is driven home from the other side.

Nuts are small enough to vanish into a workbench and soft enough to pick up a burr after a few removals. A burred or cross-threaded nut binds long before the joint is properly tight, so the screw feels solid in the hand while the panel it was meant to clamp still has play in it. Keeping ten fresh ones on the bench saves a good deal of hunting for the one that rolled away.

• Part number: 0131ER
• Thread: M4
• Standard: DIN 562, thin square nut form
• Material: steel
• Pack: ten nuts
• Single-unit version: part 131, the same M4, ST, DIN 562 nut sold one at a time
• Pairs with: the M4 screws used on SEBO machines, including the AM4 x 12 in part 0117ER

Replace one when the screw that goes through it spins without drawing the joint down, when the nut has been rounded at the corners by pliers, or when the original has simply been lost during a teardown. Fitting a clean nut restores a full, properly torqued clamp rather than a fastening that relies on friction.

This is the pack to order when searching for a SEBO M4 nut, a DIN 562 square nut for a vacuum, or a ten-pack of SEBO M4 fastenings. Compare the thread of the nut you removed before ordering, since more than one thread size appears on a single machine and the nuts look alike at a glance. Genuine SEBO parts, supplied by an authorized dealer, ship in 2-5 business days.
