Detailed Specifications Type: Nylon Insert Hex Lock Nuts Material: Grade 8 / Nut Grade C Alloy Steel – Heavy Duty Finish: Zinc-Yellow Bake, Cr+6 Plating Locking Mechanism: Nylon Insert Thread Type: UNC (Unified National Coarse) Threads System of Measurement: Inch (Imperial / US) Standards Met: ASME B18.16.6 Material Properties Our Grade 8 zinc-yellow nylon insert hex locknuts are manufactured from high-strength alloy steel, offering: Exceptional Tensile Strength: Suitable for high-stress applications with Grade 8 bolts and screws. Vibration Resistance: Nylon insert prevents loosening due to vibration and movement. Corrosion Resistance: Zinc-yellow Cr+6 plating protects against rust and corrosion. High Visibility: Yellow finish allows for easy identification during maintenance and inspections. Temperature Limitations: Suitable for applications up to 250°F (121°C) due to nylon insert limitations. 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). Order Yours Today Don't compromise on strength and reliability.
