YOU WILL NEED THE FOLLOWING ITEMS
Requires one pair of Nord-Lock washers.
All our washers are laser marked (Nord-Lock brand name, control number, type code). This is to ensure you receive genuine Nord-Lock washers and enables full traceability down to the first assembly.
PREPARATION
Nord-Lock washers always come in pairs. If your washer is accidentally separated make sure the washers are mounted cam facing cam.
Discard damaged bolts.
Do you have a tight fit between the bolt and the hole? Use the standard washer.
Do you have a loose fit between the bolt and the hole? Use the enlarged (SP) washer. Ideal for use on large/slotted holes, painted surfaces and soft materials. We recommend the use of flanged head bolts and nuts with our SP washers.
When to ask for support
FINAL CHECK
Never use a plain/flat washer with Nord-Lock washers. If you need a larger diameter washer, use the Nord-Lock SP washer.
Never divide the washers and only use one of the washers.
Make sure the washer is aligned and rest flat.
Correct installation.
