Lock Washers

Lock washers are used for creating tight assemblies with ordinary fasteners. Raptor Supplies offers a wide range of lock washers from brands like Unistrut, Vulcan-Hart, Midwest Acorn Nut, Fabory, Super-Strut, Metric Blue, Woodhead, Foreverbolt, Cooper B-Line, Disc-Lock and Armor Coat. These lock washers grab adjoining materials for preventing loosening due to vibration.

Features

  • Lock washers work in conjunction with threaded fasteners (like nuts) to prevent loosening.
  • Helical-shaped lock washers, spring lock washers & split lock washers get activated at the slightest pressure and offer a spring action.
  • Selected lock washers have serrations on their external grip surfaces (top & bottom, or just the top) for extra gripping power. This prevents loosening / shifting due to high vibration.
  • Some Belleville spring lock washers feature smaller outside diameters compared to standard spring lock washers for fitting under socket head cap screws.
  • Lock washers conform to standards like ASME (American Society of Mechanical Engineers), DIN (German Institute for Standardization), military specifications and NAS (National Aerospace Standards).
  • Most washers come in packs containing multiple pieces for easy replacement.

Disc-Lock Washer Bolts:

  • Disc-Lock washers use the wedge-locking system for preventing the loosening of bolts & maintaining joint integrity in high-stress, corrosive & vibration-sensitive applications.
  • Disc-Lock washers feature two pre-assembled washer-shaped pieces having inclined cams on one side and ridges on the other side. After installation, these two cam sides mate together and get placed between the nut & the joint material.
  • When the nut attempts to rotate loose upon vibration, the interlocking cams & the non-slip ridges of these Disc-Lock washers create a jamming effect & prevent loosening.
  • They have Delta-Protekt coating for high corrosion resistance.

Metric Blue Split Lock Washers:

  • These split lock washers have high collars for more holding surface.
  • They have a blue-coloured coating for easy metric identification.

Fabory Lock Washers:

  • These lock washers are made of spring steel, stainless spring steel, stainless steel, aluminium, bronze, phosphor bronze, silicon bronze or steel for use in diverse environments & operations.
  • They are available in helical spring, toothed, wedge, conical spring, contact, curved locking edge, curved spring & wave spring styles.

Frequently Asked Questions

How to install a lock washer?

  • Place the lock washer between the threaded fastener (like a nut) and the screw / bolt head.
  • Make sure that the lock washer press against the fastener & other adjacent surfaces and forms a tight connection. Press the fastener down to lock the grooves of a tooth lock washer with the grooves of the nut.
  • Use a wrench or ratchet to tighten the nut or threaded fastener.
  • Make sure that the teeth of the tooth lock washer are covered completely by the nut / fastener head, or that the split lock washer is slightly out of alignment to indicate tension on the threaded fastener. Users may loosen the nut / threaded fastener to adjust the washer if it is not operating correctly.

How to remove a lock washer?

  • After the operation is completed, the washer can be removed by simply removing the nut / threaded fastener that is holding the washer in place using a vise-grip or pipe wrench.
  • Use a flat screwdriver to pry the lock washer off. When removing a split washer, the screwdriver head should be placed inside the split or beneath the washer and pushed. When removing a washer having teeth, the screwdriver head should be placed under a tooth and pushed up, repeating the procedure with more teeth if required. For other lock washer types, the screwdriver head can be placed below the washer and pushed up. The washer may break during removal, depending on the amount of pressure being applied.
  • If the lock washer does not budge, use penetrating oil and repeat the previous step.
  • Some lock washers can be used multiple times easily. Other washers (split lock) can be used only 1 or 2 times. Users should not reuse a split lock washer or other damaged washers. Do not use old washers in high-stress joint applications.

What is the difference between lock washers and flat washers?

Flat washers are suitable for increasing the surface area and distributing the applied force when tightening the fastener. They can be used on the fastener's bolt & nut sides, or used as spacers where using a bolt may not be suitable.
Lock washers create tension during tightening to prevent the loosening of nuts. They are generally used on the fastener's nut side for applications involving vibrations.

Which type of lock washers has the highest vibration resistance?

Split Lock, Tooth Lock, Diamond-Coated Lock, Spring Lock and Wedge Lock type lock washers have vibration resistance in ascending or increasing order.
