Screw and washer assemblies with coarse thread - Part 5: With captive conical spring washer

Conical Spring Washers

Conical Spring Washers are used to counteract the loss of preload of a bolted connection for bolts of property classes 8.8 to 10.9. They are most effective on axially loaded short bolts where they increase the axial compliance.

It should be noted that Conical Spring Washers are highly stressed components and are therefore only recommended for static or infrequent varying load applications.

Nominal Bolt Size ranging from 2 - 30mm (0.08" - 1.18"), are available in a variety of materials and finishes:

Spring Steel
• Blank / Oiled only
• Phosphate & Oiled
• Mechanical Zinc Plating
• Mechanical Zinc Plating & Polyamid
