Disc Springs

Corrosion-Resistant Belleville Disc Springs

Made of stainless steel, these springs are more corrosion resistant than steel springs. Use them on shafts, bolts, and the ends of valves to maintain tension and separate components.

Belleville Disc Springs for Flange Bolts

Keep pipe flange connections sealed during demanding applications. When installed under flange bolt heads, these springs compensate for shock loads, vibration, and thermal expansion and contraction.

Mil. Spec. Belleville Disc Springs

These springs meet MIL-W-12133.

Corrosion-Resistant Stacked Wave Disc Springs

Made of 17-7 PH stainless steel with multiple rows of waves, these springs are more corrosion resistant than steel springs and handle greater loads than standard wave disc springs.

Corrosion-Resistant Wave Disc Springs

Made of stainless steel, these springs are more corrosion resistant than steel wave disc springs.

Corrosion-Resistant Curved Disc Springs

Made of stainless steel, these springs are more corrosion resistant than steel springs.

Notched Disc Springs

Notches make these springs more flexible than Belleville disc springs and allow liquid to flow around the spring, even while it's in use.

Washers

Belleville Spring Lock Washers

Also known as conical washers, these have a slightly cupped shape that gives them spring-like flexibility to grip tighter than split and tooth lock washers.

Belleville Spring Lock Washers for Socket Head Screws

These washers have smaller outside diameters than standard spring lock washers to fit neatly under socket head cap screws.

Metric Spring Lock Washers

The arched shape of these washers presses up against a bolt and down against a nut to prevent loosening from wear, vibration, or temperature changes.

Metric Tab Lock Washers

Bend the tab of these metric lock washers against the flats of a hex nut or bolt head to prevent the fastener and washer from turning and loosening due to vibration, wear, or changes in temperature.

Tab Lock Washers

Bend one tab against the side of the mounting surface and the other tab against the flats on a bolt or nut to prevent both the fastener and washer from turning and loosening in high-vibration applications, such as a motor mount.

Triple-Wave Washers

With three points of surface contact, these washers provide more stability than single-wave washers.

Metric Single-Wave Washers

These curved, flexible washers act like springs to compensate for tolerance variations and uneven surfaces.

Single-Wave Washers

These curved, flexible washers act like springs to compensate for tolerance variations and uneven surfaces.
