INDENTED HEXAGON Anti Loosening Screw, High Vibration Resistant Hex Socket Locking Fastener for Industrial Equipment
Product Overview
INDENTED HEXAGON Anti Loosening Screw is a specialized locking fastener designed to eliminate screw loosening caused by equipment vibration, frequent startup-stop operation and high-load shaking. Different from standard hexagon screws, its indented concave hex head optimizes wrench fitting stability; matched with pre-coated anti-loose nylon glue on full threads, it realizes mechanical indent locking + chemical thread locking dual safety structure.
This series of indented hexagon anti-loose screw targets B-end industrial manufacturers, focusing on high vibration assembly scenarios where ordinary fasteners easily fall off, effectively reducing equipment maintenance frequency and hidden safety hazards brought by loose connections.
Core Features & Competitive Advantages
-
Dual Anti-Loosening Core Design
Our INDENTED HEXAGON Anti Loosening Screw adopts indented hexagon positioning + nylon thread lock coating double protection. The concave indent structure prevents tool slipping during installation, the elastic nylon layer locks thread clearance tightly under vibration, anti-loose service life 3x longer than common hex locking fasteners. -
High Strength Raw Material Option
Available stainless steel 304/316, grade 8.8/10.9/12.9 alloy steel, tensile strength up to 1220MPa, adapt high-load heavy industry assembly. -
Standard & Custom Size Support
Complete metric specifications M4-M24, full thread/half thread optional; support custom length, surface treatment (black oxide, zinc plating, passivation) per client drawings. -
Reusable Locking Performance
The anti-loose coating can withstand 2-3 disassembly cycles without losing locking effect, perfect for equipment requiring regular overhaul. -
Anti-Corrosion Surface Process
Custom zinc plating, nickel plating, black oxidation surface to resist moisture, dust, weak acid environment, extend service life of indented hexagon anti-loose screw.
