5/8 Double Coil Spring Lock Washer HDG

PRODUCT OVERVIEW

This 5/8 hot-dip galvanize double coil lock washer is an industrial fastening component used under a nut or bolt head to help maintain tension in an assembled joint. The double coil design is made from round wire formed into two coils, giving the washer additional movement compared with a single-coil lock washer.

Double coil lock washers are commonly used where joined materials or assemblies may be affected by vibration, corrosion or dimensional movement over time. In applications such as wood pole-line construction, the washer helps preserve fastening tension as materials expand, contract, shrink or settle around the fastener.

KEY PRODUCT CHARACTERISTICS

• Tengco item number: PWD58.6-H
• Product type: double coil lock washer
• Nominal bolt size: 5/8 inch
• Finish: hot-dip galvanize
• Constructed from round wire formed into two coils
• Designed for use beneath a nut or bolt head in fastening assemblies
• Intended to help reduce loosening by maintaining tension in the joint

The hot-dip galvanize finish is an important purchasing detail for buyers sourcing components used in exposed industrial or utility environments. This finish should be evaluated alongside the fastener, mating components and project requirements to confirm the correct washer configuration for the application.

TYPICAL APPLICATIONS

This type of 5/8 double coil lock washer is commonly associated with fastening assemblies where vibration, outdoor exposure or material movement may affect joint stability. Applications should be reviewed against the full assembly design, mating fasteners and customer specifications.

Typical applications include:

• Utility pole hardware and line construction assemblies
• Wood pole-line fastening where materials may expand, contract or shrink
• Trailer and transportation equipment exposed to road vibration
• Heavy equipment frames, mounts and structural brackets
• Industrial fastening assemblies that require a lock washer under a nut or bolt head

For utility and line construction buyers, the double coil design can be useful in assemblies where the fastened material may change dimension over time. In transportation and heavy equipment applications, this general type of washer is often selected to help manage loosening concerns associated with vibration and movement.
