Installation Tips

For optimal performance when using Grade 8 zinc-yellow nylon insert hex locknuts:

• Ensure the nut size matches the bolt or screw size.
• Use with Grade 8 bolts and washers to maintain assembly strength.
• Thread the nut onto the bolt by hand to avoid cross-threading.
• Tighten using the appropriate wrench or socket for the hex size.
• Follow recommended torque specifications for Grade 8 fasteners.
• Avoid over-tightening to prevent stripping threads or damaging the nylon insert.
• Do not reuse nylon insert locknuts; replace them if removed.
• Not recommended for high-temperature applications exceeding 250°F (121°C).
