SAF Caliper Mounting Bolt M16x55
$20.00
SAF caliper mounting bolt with M16 x 1.5 thread, 55mm nominal length and a collared head for selected Intradisc trailer brake assemblies. This is the caliper fixing bolt, not the separate centring bolt; confirm the axle and removed fastener before fitting.
Part number AP7598.
Description
Overview
The SAF Caliper Mounting Bolt is an M16 x 1.5 x 55mm collared fastener used to secure disc brake calipers on compatible SAF-Holland trailer axles. It forms part of the caliper mounting arrangement, holding the brake assembly securely against its mounting support.
This bolt suits selected SAF Intradisc applications using WABCO and Knorr-Bremse calipers. Its collared design distinguishes it from the separate centring bolt used in the same mounting arrangement.
Features
- M16 x 1.5 metric fine thread.
- 55mm nominal bolt length.
- Collared mounting design for caliper fastening.
- Used with selected WABCO PAN19-1 and Knorr-Bremse SN6/SN7 brake assemblies.
- Individual replacement fastener for caliper removal and refitting.

Compatibility and Fitment
This mounting bolt suits SAF axle configurations that specify the M16 x 1.5 x 55mm collared caliper fastener. Applications include selected Intradisc assemblies fitted with WABCO PAN19-1 or Knorr-Bremse SN6 and SN7 calipers.
Before ordering, compare the removed bolt’s thread, length, collar profile and mounting position. The separate centring bolt also uses an M16 thread but performs a different locating function.
Do not substitute this bolt for M18 caliper fasteners used on other SAF axle generations.

Why Choose ICS Trailers
SAF disc brake assemblies use different caliper mounting fasteners depending on axle generation and locating position. The M16 x 1.5 x 55mm collared bolt must match the existing arrangement, particularly where a separate centring bolt is also fitted.
ICS Trailers can assist with identifying the correct mounting hardware for your brake assembly.
- Compare the M16 thread, 55mm length and collar configuration before ordering.
- Send through the axle identification plate, caliper model or removed bolt measurements if you need assistance identifying the correct fastener.
