Description

DESCRIPTION

Cone Lock HCL Nut - High Tensile Zinc Plate 1/4UNC x (Box=100)

(Price per unit)

Hex Conelock nuts feature a conical top and a flat bearing surface on the bottom, with chamfered corners for ease of use.

Their locking mechanism comes from a slight distortion in the top threads, allowing them to resist loosening under heavy vibration and shock.

Because only the bottom surface is flat and the locking feature is at the top, these nuts are designed to be installed in one direction only (top facing up), making them a one-way lock nut.

Key features:

  • Conical top with flat bottom bearing surface
  • Thread distortion provides strong locking action
  • Resistant to vibration and shock loads
  • One-way installation (top must face up)
  • All-metal construction (no nylon insert)

Advantages:

  • Not affected by high temperatures
  • Resistant to chemicals compared to nylon-insert lock nuts
  • Durable and suitable for demanding environments

Common uses:

  • Automotive industry
  • Agricultural equipment
  • Metalworking applications

Their cone shape also helps ensure correct positioning during automated assembly, which makes them especially suitable for high-volume production.

Using a Conelock: Conelocks are a locking nut, they will wind on freely until they hit the triangular cone shape top with the dots, then a tool is required to tighten nut

Also known as: Prevailing Torque Lock Nuts, Stover Nuts, Grade C Lock Nuts, Automation Lock Nuts, Autolock Nuts, Crownlock Nuts, Unitorque Nut

Nuts must be selected to match a compatible bolt grade and material system to ensure proper strength and performance.

Finish
ZINC PLATED (RoHS Compliant)
 
Zinc Plated is the most common fastener of plating due to its the low cost and shinny bright silver finish. A thin layer of zinc is applied by either electroplating or mechanically. It is intended to be used internally. If corrosion is a concern, choose from the Stainless steel range for external use.
