PA66 Slotted pan head screw Overview
PA66 (Polyamide 66, or Nylon 66) Slotted Pan Head Screw is a popular, general-purpose plastic screw known for its excellent toughness, low friction, and electrical insulation. The Pan Head provides a wide bearing surface for secure clamping, while the Slotted Drive allows for simple installation using basic tools.
I. Overview and Design
| Feature | Detail | Purpose |
| Material (PA66) | Polyamide 66 (Nylon 66). A high-strength, durable engineering plastic. | Provides excellent mechanical properties, electrical insulation, and resistance to abrasion at a cost-effective price point. |
| Head Style (Pan Head) | Features a gently rounded top and vertical sides, maximizing the bearing surface for strong clamping and pull-through resistance. |
Product Parameters
PA66 Slotted Pan Head Screws typically follow metric standards for slotted pan head screws, such as ISO 1580 or similar industry specifications.
| Nominal Diameter (d) | Thread Pitch (P) | Head Diameter (D) | Head Height (K) | Slot Width (N) |
| M2 | 0.4 mm | 4.0 mm | 1.3 mm | 0.5 mm |
| M3 | 0.5 mm | 6.0 mm | 2.0 mm | 0.8 mm |
| M4 | 0.7 mm | 8.0 mm | 2.6 mm | 1.0 mm |
| M5 | 0.8 mm | 9.5 mm | 3.3 mm | 1.2 mm |
| M6 | 1.0 mm | 11.0 mm | 3.9 mm | 1.6 mm |
| M8 | 1.25 mm | 14.0 mm | 5.2 mm | 2.0 mm |
Key Features
PA66 Slotted Pan Head Screws offer a robust set of properties suitable for a wide range of assemblies:
Toughness and Impact Resistance: Highly resistant to breakage and damage from impact, making it very durable.
Electrical Insulation: Excellent dielectric properties, crucial for isolating electrical circuits and components.
Abrasive Resistance: Good resistance to wear and abrasion, useful in dynamic or frequently adjusted assemblies.
Corrosion Immunity: Will not rust or cause galvanic corrosion.
Wide Bearing Surface: The Pan Head provides excellent pull-through resistance for securing soft materials or thin panels.
Key Polyamide Nylon (PA6) Properties
Applications
PA66 Slotted Pan Head Screws are primarily used in medium-duty, non-metallic fastening:
Electronics and Appliances: Securing internal components, mounting circuit boards, and attaching covers where electrical isolation is necessary.
Automotive Interiors: Fastening plastic trim, non-structural panels, and cosmetic components.
Marine: Used in internal cabin fittings and electronics where resistance to damp environments is required without rust.
General Assembly: Securing guards, small boxes, and plastic components in machinery and equipment.
Advantages
| Category | Advantage (Pro) | Disadvantage (Con) |
| Performance | High mechanical strength (for an unreinforced polymer). Excellent toughness and non-conductivity. | Moisture Absorption: Nylon absorbs water, which can affect dimensions and slightly reduce strength over time. |
| Design | Pan Head offers superior load distribution. Highly cost-effective and widely available. | Slotted Drive Limitation: Provides low torque transmission and is prone to tool slip (cam-out). |
| Environmental | Resistant to oils and fuels. Lightweight. | Chemical Resistance: Susceptible to strong acids, bases, and oxidizing agents. |
