OVERVIEW
Factory flat-head bolt for the original belt tensioner
N-911-894-01 is a Genuine VW/Audi M10 x 60 flat-head bolt with an internal multipoint drive. It secures the specified original belt-tensioner or damper attachment in the confirmed applications below.
The belt-drive arrangement uses several bolt and pulley types. The correct flat-head profile, nominal length and original joint must match; this individual fastener is not a tensioner assembly and does not include a pulley, bearing or belt.
Technical details
- Complete factory number: N-911-894-01.
- Factory specification: M10 x 60 mm flat-head internal-multipoint bolt.
- Design: Low head profile with recessed multipoint drive and threaded shank.
- Quantity supplied: one individual bolt.
M10 x 60 gives nominal thread diameter and fastener length. No unverified thread pitch, bit size, strength class, tightening torque or shipping measurement is stated.
Common reasons to replace
- Damaged multipoint recess that prevents secure tool engagement.
- Damaged threads, a bent shank or an impaired head seating surface.
- Missing or incorrect hardware found during belt or tensioner service.
Belt noise, poor tracking or tensioner movement requires diagnosis of the belt, pulley bearings, damper and mounting surfaces. A new bolt alone does not repair a worn tensioner or bearing.
