N-100-632-05 Genuine VW/Audi Collared Hex Bolt - M8 x 20 mm

Genuine VW/Audi collared hex bolt, part number N-100-632-05. This factory hardware provides the threaded attachment and bearing surface specified for its mounting point. The applications listed below identify it at the left rear-seat child-restraint anchor plate. It is also cataloged for other assemblies, so the original part number and the specific attachment position must determine selection.

Technical details

• Original part number: N-100-632-05 / N10063205.
• Published nominal size: M8 x 20 mm. M8 identifies the nominal thread diameter; 20 mm is the published bolt length.
• External hex head with an integral collar, supplied individually as pictured.
• The collar provides the fastener's contact surface at the prescribed mounting point. Preserve the original hardware arrangement and any separately specified companion pieces.
• One bolt is supplied. Anchor plates, seat frames, brackets and other assembly hardware are separate.
• Vehicle compatibility does not mean this bolt replaces every M8 fastener on that vehicle. Thread size alone does not establish the required head geometry, strength or mounting application.

Common reasons to replace

Replacement is appropriate when the original bolt is missing after disassembly, has damaged threads, has a rounded drive head or shows corrosion or damage that prevents correct seating. Incorrect replacement hardware can also require correction during repair of the original mounting assembly.

Inspect the attachment and its mating threads before installing new hardware. A loose fastener may indicate a damaged bracket, distorted anchor plate or compromised threaded mounting point. Replacing the bolt alone does not restore a damaged seat or restraint attachment. Hardware exposed to impact or deformation requires evaluation according to the vehicle's repair procedure.

Installation and service notes

Use the factory procedure for the exact assembly and vehicle. Record the original bolt position before removal, support any component being released and inspect the threads for cross-threading or debris. Start the replacement by hand and ensure the collar seats against the prescribed bearing surface.

Use the specified tightening procedure for that mounting point. Do not derive torque from the M8 size or transfer a specification from an unrelated assembly. Follow any instructions for replacement of companion hardware, thread treatment and tightening sequence.

For the child-restraint anchor applications below, confirm the anchor plate is correctly positioned and securely retained after assembly. Do not compensate for damaged threads or distorted components by adding washers or substituting a longer bolt. The mounting assembly must meet the factory repair requirements before it is returned to service.

Fitment

Confirm the original part number and the anchor-plate mounting position before ordering. One bolt is supplied.
