OEM Sealing Screw Stainless Steel Waterproof Machine Screw O Ring Anti Corrosion Precision Fastener For Auto Battery Electronic Equipment Supplier, Factory

Product Overview

Our Sealing Screw is a customized integrated waterproof Machine Screw designed to eliminate liquid, dust and moisture leakage in precision assembly scenarios. Unlike ordinary machine screws without sealing structure, this Sealing Machine Screw comes with pre-installed rubber O-ring under screw head, forming full 360° hermetic seal after locking, greatly reducing equipment failure caused by water and corrosion.

We produce full-size standard & non-standard Sealing Screw, raw material covers SS304, SS316, carbon steel, brass, fully compliant with industrial assembly standards for new energy auto battery packs, mechanical equipment, electronic control cabinets and automation machinery.

Core Features & Competitive Advantages

1. Integrated Sealing Structure

• One-piece bonded O-ring matches screw head groove, no extra gasket needed, installation efficiency improves by 60% compared with split sealing solutions
• The core Sealing Screw design keeps stable sealing pressure under long-term vibration, zero water leakage under IP67 waterproof grade

2. Superior Material & Anti-Corrosion Performance

• Main body of Machine Screw: stainless steel material, rust-proof for humid workshop, outdoor equipment assembly
• O-ring: silicone / EPDM optional, resistant to oil, weak acid, high & low temperature (-40℃~120℃)

3. Rich Drive & Head Types for Customization

Pan head, hex socket, cross slot, torx drive Sealing Machine Screw are available, M2-M12 full thread specifications to match different installation space

4. Stable Precision Tolerance

All Sealing Screw threads controlled within ±0.02mm tolerance, consistent locking torque, no thread slipping during mass assembly

5. Factory Direct Custom Support

Support OEM/ODM size, surface treatment, color O-ring customization, mass production capacity over 5 million pieces per month, stable delivery cycle for B-end bulk buyers
