Oil Plug Screws with Hole – Technical Description & Functional Overview
Oil plug screw with hole are precision-engineered fasteners designed for fluid drainage systems, combining secure sealing with enhanced functionality through integrated apertures. These specialized plugs serve critical roles in maintenance, monitoring, and system optimization across automotive, industrial, and heavy equipment applications.
Core Features & Design Specifications
1. Aperture Configurations
-
Axial Through-Holes (1–3mm diameter): Enable visual inspection or controlled fluid flow
-
Radial Cross-Drills: Improve drainage efficiency or venting
-
Multi-Port Designs: For high-flow applications (e.g., gearbox drains)
2. Material & Construction
-
Metallurgy:
-
Stainless steel (304/316) for corrosion resistance
-
Aluminum (6061-T6) for weight-sensitive uses
-
Technical Performance Data
-
Thread Standards: M12×1.25 to M24×2.0 (metric), ½”-14 to 1″-12 (SAE)
-

Key Applications
-
汽車: Engine oil pans, differentials, transfer cases
-
Heavy Machinery: Hydraulic reservoirs, compressor crankcases. Oil plug screw with hole
-
Aerospace/Marine: Corrosion-prone fluid systems
Advanced Variants
-
Smart Plugs: RFID-enabled for service tracking
-
Self-Sealing: Spring-loaded valves prevent spills

Selection Guide
-
Choose hole type based on need (inspection vs. venting)
-
材料選擇: Consider fluid compatibility/vibration
-
Seal type: Crush washers for high pressure, O-rings for reuse
These Oil plug screw with hole transform basic drainage into a proactive maintenance feature, with hole designs enabling everything from leak checks to wear debris analysis. For critical applications, specify magnetic or sensor-equipped versions to enable condition-based monitoring.
