Captive Screws
Stainless Steel Captive Screw Anti Lost Retaining Fastener for Electrical Enclosure Industrial Machinery and Automotive Assembly
1. Product Overview
Captive Screw is a professional retaining fastener specially engineered to stay attached to panels and components even after loosening. Different from traditional screws, this captive Screw effectively prevents fastener loss during installation, inspection and daily maintenance. It has become a preferred fastening solution for industrial manufacturing, electronic equipment, automotive and electrical enclosure industries. Our standard and customized captive Screw strictly follow industrial production standards, with stable quality and wide compatibility.
2. Core Features & Advantages
- Anti-lost Structure Design: The exclusive shaft structure makes the captive Screw fixed on the assembly permanently, no loose or missing screws, greatly reducing equipment failure risks.
- High Durability: Most captive Screw are made of premium steel and stainless steel materials, featuring high tensile strength, wear resistance and long service life.
- Corrosion Resistance: Surface anti-rust treatment ensures the captive Screw works stably in humid and harsh working environments.
- High Assembly Efficiency: No need to pick up scattered screws, greatly shorten assembly time and reduce labor costs for mass production.
- Vibration Resistance: The tight fit structure enables the captive Screw to keep firm connection under long-term vibration, suitable for running mechanical equipment.
