Essential Air Removal for Hydraulic Cylinders

Master Cylinder Bleed Screw products remove trapped air from hydraulic cylinder chambers. These screws help maintain smooth cylinder operation without unstable movement. Our products support thread sizes from M4 to M60×2, with overall lengths ranging from 8mm to 180mm. These components enable effective bleeding for reliable hydraulic system performance. Proper air removal improves force transmission consistency and helps maintain stable system operation.

Precise Hexagon Sockets for Smooth Operation

Hexagon socket fit tolerance directly affects tool engagement performance during installation. We control hexagon socket fit tolerance within ±0.01mm. For larger specifications, we guarantee outer profile tolerance of ±0.02mm. Precise hexagon socket dimensions allow hex keys to engage smoothly without slipping. This reduces installation difficulties and prevents connection issues caused by improper tool engagement.

High-Precision Milling for Hexagon Features

Our hexagon socket machining uses high-precision milling processes to maintain dimensional accuracy. We perform regular equipment calibration, maintenance, and timely replacement of tools and fixtures. During production, we conduct first-article inspections and regular in-process inspections to ensure stable quality. If abnormalities occur, we stop production immediately and implement corrective actions. Our company holds IATF16949 automotive quality management system certification. This ensures controlled production management for Master Cylinder Bleed Screw products from development through mass production.

Strict Quality Requirements for Hydraulic Applications

We understand the strict sealing and reliability requirements of hydraulic applications. Every batch of Master Cylinder Bleed Screw products completes dimensional, appearance, and thread accuracy inspections before shipment. We provide complete inspection documentation with every order. Customers can also arrange third-party agencies for on-site inspection and cooperate with customer process and product audits. Prototype development typically takes 15 to 30 days, while mass production requires 30 to 60 days. Repeat orders usually have shorter lead times because production processes and fixture data are already established.
