Nylon Cable Gland Locknut
Nylon cable gland locknuts secure threaded cable entries to enclosure walls, junction boxes, and machinery panels. Molded from virgin polyamide (PA66) resin via precision injection tooling, these fasteners maintain mechanical retention, ground continuity, and seal integrity under industrial vibration. Designed to interface seamlessly with standard metric, PG, and NPT thread profiles.
Product Overview
Nylon cable gland locknuts secure threaded cable entries to enclosure walls, junction boxes, and machinery panels. Molded from virgin polyamide (PA66) resin via precision injection tooling, these fasteners maintain mechanical retention, ground continuity, and seal integrity under industrial vibration. Designed to interface seamlessly with standard metric, PG, and NPT thread profiles.
Key Features
Raw Material Integrity: Molded from 100% virgin PA66 (Polyamide), offering high tensile strength, rigidity, and resistance to environmental stress cracking.
Vibration-Resistant Threading: Internal buttress or standard profiles engineered with controlled pitch tolerances to prevent self-loosening under continuous machine operation.
Flammability Rating: Standard UL94 V-2 compliance; flame-retardant UL94 V-0 compounds available for high-safety installations.
Chemical Resistance: Stable exposure performance against industrial oils, grease, salt water, alcohol, and weak acids.

OEM & ODM Customization
In-House Tooling: Mold design and CNC machining capabilities support non-standard thread pitches, customized widths, or embossed brand logos.
Resin Formulation: Custom compounding for enhanced UV resistance or specific low-temperature impact strength.
Industrial Packaging: Bulk bagging or specific kit packaging tailored for automated assembly lines.
Quality Control
Dimensional Verification: Automated optical sorting and precision caliper checks maintain inner diameter, thickness, and thread tolerances within +/- 0.05 mm.
Torque Testing: Routine destructive and non-destructive bench tests verify that thread stripping thresholds exceed standard field installation requirements.
Resin Inspection: Incoming virgin PA66 resin batches undergo melt flow index and density testing before production.
Documentation Support: Material Data Sheets (TDS), RoHS declarations, and batch inspection reports supplied upon order execution.
Frequently Asked Questions
Q: Are these locknuts compatible with metallic cable glands?
A: Yes, provided the thread standard, size, and pitch match precisely (e.g., metric locknut paired with a metric threaded gland). Verify recommended torque limits to avoid thread stripping.
Q: What is the practical difference between UL94 V-2 and V-0 ratings?
A: V-2 indicates the polymer self-extinguishes within 30 seconds on a vertical specimen, allowing burning drips. V-0 grades self-extinguish within 10 seconds and do not emit flaming drips.
Q: Do black locknuts offer outdoor UV protection?
A: Yes, standard black (RAL 9005) variants incorporate carbon black additives for baseline UV resistance. For long-term direct sunlight exposure, request dedicated UV-stabilized formulations.
Q: What is the minimum order quantity (MOQ) for custom thread sizes?
A: Standard catalog dimensions feature flexible batch minimums. Non-standard or custom thread designs typically require a minimum order quantity of 5,000 pieces per production run.
Q: What is the standard production and shipping lead time?
A: In-stock standard items ship within 3 to 5 business days. Production runs for custom colors or unique dimensions require 15 to 20 days.
Q: Do you supply matching cable glands and accessories?
A: Yes. We manufacture complete matched component sets including nylon cable glands, locknuts, and Neoprene sealing washers.
