Description

Overview

M16 nyloc nut secures the mounting connection on compatible trailer air spring assemblies. Its 1.5mm fine thread matches the mounting stud used on the SAF 2619V air bag application, while the nylon insert adds prevailing resistance against loosening under suspension movement and road vibration.

Features

• M16 diameter with 1.5mm fine thread pitch
• Nylon insert locking collar
• Zinc-coated steel construction
• 24mm hex size for standard workshop tooling

Specifications and Materials

This hex lock nut has an M16 x 1.5 metric fine thread, zinc-coated steel body and non-metallic locking insert. Its standard-style dimensions are approximately 24mm across flats and 16mm overall height.

Part number: 1015863.

See the ISO 10512 fine pitch prevailing torque nut standard

Compatibility and Fitment

Confirm the mounting stud is M16 with a 1.5mm pitch before fitting. The main ordering mistake is substituting a standard M16 x 2.0 coarse thread nut, which will not correctly engage the fine air spring mounting thread. Clean the stud and check for damaged, flattened or corroded threads before assembly.

Compliance and Safety

Depressurise the air suspension and support the trailer before loosening air spring mounting hardware. Do not force this nut onto a coarse, crossed or damaged thread. Tighten it to the air spring or suspension manufacturer’s specified procedure, and replace the nut if the nylon insert no longer provides firm locking resistance.

Trailer Applications

Workshops use this fine thread nyloc nut when fitting or servicing the matching SAF 2619V air spring on Intradisc and Intradrum trailer suspension arrangements. It suits overslung and underslung installations where the air spring mounting stud uses the specified M16 x 1.5 thread.

Why Choose ICS Trailers

Fine and coarse M16 threads look nearly identical at a glance, but fitting the wrong pitch can damage the air spring stud and delay the repair. ICS Trailers can help compare the old nut, stud thread and air spring details before ordering. Check the surrounding mounting plate, washers and air spring connection during the same repair so worn or corroded hardware is not reused.
