Sealing Screw Carbon Steel Waterproof Self Sealing Screw For Automotive Battery Pack Machinery Equipment Fastener
Product Overview
Sealing Screw also known as self sealing screw, is a special integrated sealing fastener combining screw body and elastic sealing washer. Unlike ordinary machine screw, our waterproof Sealing Screw forms a fully closed compression seal after tightening, effectively blocking water, oil, dust and corrosive gas penetrating into equipment interior.
Our factory focuses on industrial grade Sealing Screw manufacturing, all leak proof sealing screws pass strict tightness test, widely applied in automotive battery pack, automation robot joint, new energy equipment, general machinery cabinet and other industrial assembly scenarios. Compared with ordinary screws with separate gaskets, integrated Sealing Screw avoids gasket falling off during installation, greatly improving assembly efficiency and long-term sealing stability.
Core Advantages & Differentiations
-
Integral Molding Sealing Structure
The elastic sealing ring is firmly fixed on screw head, our Sealing Screw will not shift or drop during high-frequency disassembly, permanent leak proof performance. -
Superior Rust & Corrosion Resistance
All standard Sealing Screw are made of high-quality carbon steel with zinc plating surface treatment, anti rust, anti oxidation, adapt to humid workshop and outdoor mechanical environment. -
Precision Thread & Strict Tolerance
Thread of each Sealing Screw is cold extruded with ±0.02mm tolerance, smooth screwing without slipping thread, match perfectly with standard mounting holes of auto and machinery parts. -
Wide Temperature Adaptability
The sealing washer matched with our Sealing Screw maintains stable elasticity under -40℃ to 120℃, no hardening or cracking in long-term use. -
Cost Saving For Bulk Procurement
Direct factory supply of industrial Sealing Screw, support customized size and surface treatment, large order gets favorable wholesale price, reduce overall assembly cost for buyers.
