Stainless Steel PAN HEAD SIX LOBE Anti Loosening Screw Vibration Resistant Fastener for Automotive Electronics Machinery
Product Overview
PAN HEAD SIX LOBE Anti Loosening Screw is a professional anti-vibration locking fastener specially developed for high vibration industrial assembly scenes. It integrates two core advantages: six lobe torx drive structure and nylon patch anti-loosening coating, perfectly making up for the defect that ordinary pan head screws are easy to loose under continuous mechanical shaking.
Different from traditional Phillips or slotted pan head fasteners, the six lobe inner groove can bear larger tightening torque without slipping; the special nylon adhesive layer on the thread forms friction locking force after screwing, double protection to prevent automatic loosening during equipment operation.
This series of six lobe pan head anti loosening screw is widely matched with automated assembly lines, precision electronic equipment, auto interior parts, robot joint fixing and engineering machinery. We provide full standard sizes and non-standard customized processing, fully meet mass production procurement demands of B-end manufacturers.
Core Features & Competitive Advantages
-
Dual Anti-loosening Structure, Zero Looseness Failure
Our PAN HEAD SIX LOBE Anti Loosening Screw adds imported nylon patch on full thread. After installation, the nylon layer deforms to generate continuous friction, resist vibration impact from machine running, avoid screw falling off or loose gap. Ordinary pan head six lobe screws without anti-loose coating can not reach this locking effect.
-
Six Lobe Torx Drive, High Torque & Anti-slip
The six-lobe inner recess evenly distributes stress when tightening, greatly reduce cam-out slip phenomenon. Workers and automatic screwdrivers can complete high-strength fastening efficiently, improve assembly efficiency by 30% compared with cross recess screws.
-
Low Profile Pan Head, Beautiful & Space-saving Installation
Round smooth pan head occupies small installation space, will not scratch equipment shell, suitable for surface exposed assembly requirements of electronics and automotive interiors.
-
Multiple Material & Surface Treatment Options, Long Service Life
Optional raw materials: 304/316 stainless steel, Grade 8.8/10.9 alloy steel; surface treatment includes zinc plating, black oxide, passivation, salt spray resistance up to 500-1000 hours, adapt humid, high temperature industrial environment.
5. Full Size Customization Support
Complete standard sizes M2-M12, customizable length, head thickness, thread pitch, nylon coating coverage area, one-stop OEM service for B-end buyers.
