Thin Hex Gland Locknut
The Thin Hex Gland Locknut secures cable glands in space-constrained industrial enclosures, switchgear, and machinery. Designed with a reduced profile compared to standard hex nuts, it provides reliable thread engagement and retention where internal clearance is limited.
Product Overview
The Thin Hex Gland Locknut secures cable glands in space-constrained industrial enclosures, switchgear, and machinery. Designed with a reduced profile compared to standard hex nuts, it provides reliable thread engagement and retention where internal clearance is limited.
Key Features
Low-Profile Architecture: Reduced thickness allows installation in tight internal spaces without interfering with adjacent components.
Precision Threads: Clean, burr-free metric, PG, NPT, and G threads ensure smooth engagement and prevent cross-threading during assembly.
Vibration Resistance: Manufactured with parallel faces to maintain uniform clamping force against enclosure walls under operational vibration.
Material Integrity: Solid construction from corrosion-resistant brass, stainless steel, or polyamide provides mechanical stability across diverse operating environments.

Frequently Asked Questions
Q: How do I select the correct locknut size?
A: Match the locknut thread specification directly to the mounting thread of your cable gland (e.g., an M20 gland requires an M20 thin locknut).
Q: Why use a thin locknut instead of a standard nut?
A: Thin locknuts are engineered for panels with limited internal clearance where standard nuts cause assembly interference.
Q: Are these locknuts reusable?
A: Metal variants (brass and stainless steel) can be uninstalled and reused if threads remain undamaged. Note for Stainless Steel: Apply a light thread lubricant or anti-seize compound prior to re-installation to prevent potential thread galling. Nylon variants should be inspected for wear before reuse.
Q: What is the minimum order quantity (MOQ)?
A: Standard sizes maintained in stock have low MOQs. Custom threads or special material runs are subject to agreed production minimums.
Q: What are the standard delivery lead times?
A: Ex-stock standard items ship within 3 to 5 business days. Custom production orders typically require 15 to 25 days.
Q: Can these withstand high vibration?
A: Yes. When torqued to specified limits against a flat enclosure surface, parallel faces distribute clamping stress to resist loosening.
