Tiny Components for Precision Instruments

Miniature Instrument Bleed Screw products are designed for air and fluid venting in precision instruments. Their compact size makes them suitable for installation in extremely limited spaces. Our products support thread sizes from M2×0.25 to M12, with overall lengths ranging from 3mm to 30mm. These screws enable precise venting in compact instrument designs and help maintain accurate pressure control in sensitive measurement equipment.

Smooth Tips and Accurate Threads

Tip roughness and thread accuracy are key performance factors for miniature bleed screws. We control tip roughness to Ra0.4μm and guarantee Grade 6g thread accuracy. For larger specifications, we control dimensional tolerance within ±0.01mm. Smooth tips create precision seals with valve seats. This helps prevent micro-leakage after instrument venting operations and improves long-term reliability.

Specialized Micro-Part Machining Capabilities

Micro-part machining requires high-precision equipment and specialized machining processes. Our Tsugami S206A and Citizen A20N Swiss-type automatic lathes specialize in miniature precision component production. These machines complete turning, threading, and tip forming operations in a single setup. Our factory has implemented digital production management systems with complete process data records. Our company has extensive experience producing Miniature Instrument Bleed Screw products for semiconductor equipment and precision instrument industries.

Professional Pre-Sales Technical Support

Our pre-sales technical support is thorough and responsive. After receiving customer drawings, we evaluate micro-structure processing feasibility and provide free process optimization recommendations. Prototype development typically takes 15 to 30 days, while mass production requires 30 to 60 days. Repeat customers benefit from shorter delivery times because process data and production experience are already available. We support both small-batch customization and large-volume production. We can also provide special surface treatments according to customer requirements for Miniature Instrument Bleed Screw applications.
