Oil plug screw with hole

O processo de encabeçamento a frio é um dos novos processos para a maquinagem sob pressão com menos ou nenhum corte
metal. É um método de processamento que utiliza a deformação plástica do metal sob a ação de
forças externas e, com a ajuda de moldes, redistribui e transfere o volume de metal para formar
as peças ou os espaços em branco necessários. O processo de encabeçamento a frio é o mais adequado para a produção de
elementos de fixação, tais como cavilhas, parafusos, porcas, rebites, cavilhas, etc.

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)

• Pressure Rating: 50–150 psi (varies by seal design)

• Temperature Range: -40°C to +260°C (-40°F to +500°F)

Key Applications

• Automóvel: 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

• High-Flow: Multi-hole designs for rapid drainage

Selection Guide

1. Choose hole type based on need (inspection vs. venting)

2. Material selection: Consider fluid compatibility/vibration

3. 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.
