Product details
Description
Secure your heavy-duty mechanical, automotive, and industrial assemblies with the Makers Bolt 5/8 Inch - 18 Grade 8 Hex Nylon Insert Lock Nut 10 Pack. Designed for applications requiring high tensile strength and superior vibration resistance, these fasteners feature an integrated non-metallic nylon collar at the top edge.
When threaded onto a matching bolt, the nylon ring deforms elastically to create strong frictional prevailing torque, preventing the nut from loosening under heavy operational stress or vibration. Crafted from heat-treated medium carbon alloy steel and finished with a durable yellow zinc plating, these fasteners offer moderate corrosion resistance for demanding environments.
Each nut requires a 15/16 inch wrench and conforms strictly to industry standards for reliability and safety in high-stress engineering projects.
How to use
- Pair exclusively with matching 5/8 inch - 18 fine thread Grade 8 bolts or threaded rods.
- Thread the nut onto the bolt until the nylon collar engages the threads, then tighten using a 15/16 inch wrench to the required torque specification.
- Note that these are single-use locking nuts; replace them rather than reusing if removed, as locking torque decreases after the initial installation.
Ingredients
Heat-treated medium carbon alloy steel substrate with yellow zinc conversion coating and integral polymer nylon insert collar.
