Starlock Washers

Starlock washers are a method of securing a threaded pin inside a tube. They are used to fix parts on shafts, axles or rods with a diameter from 2 to 25 mm. Use in rigging operations is permitted. This is an improved version of traditional retaining rings.

Installation is quick, without rings or grooves: to install, simply press on the ring of the Starlock washer. Automated installation is possible using a tool with a magnetic head and attachments.

Operating principle

The Starlock retaining washer locks onto irregularities on the surface of the rod that are imperceptible to the naked eye. The retainer fits with increased tightness, so it cannot be removed without deformation. The load capacity reaches 60 tons. Fasteners are made from high-strength materials: stainless steel without additional coating, as well as spring steel coated with zinc and varnish for protection against moisture and environmental exposure. Starlock retaining washers are manufactured in series starting from a 2 mm diameter.

4 types of caps are used to close the rod:

• Dome;
• Axial;
• Axial, increased height;
• Nylon.

Application areas

Starlock retainers are used in the following fields:

• Automotive industry — for securing wheels or the driver’s seat.
• Medicine — for fastening diagnostic equipment.
• Household use — for installing and securing handles, ironing boards.
• Children’s products, including toys.
• Installation of insulation coating in residential and commercial construction.
• Fixing components in electrical and photographic equipment.
• Manufacturing of cabinet and frame furniture.
• Construction.

Operating advantages

The advantages of installation include:

• Withstand loads up to 60 tons.
• The connection remains secure for more than 3 years.
• Do not require heat treatment.
• Automatic installation is possible.

Selection

Selection is based on the operating characteristics of the retaining washer: internal diameter in millimeters, rated load capacity and other parameters. Operating conditions must be taken into account to prevent damage from moisture or low temperatures. It is recommended to select the fastener with consideration of recommendations from cargo transportation specialists.
