Imperial Pozi Pan Head Screws.

What are Imperial Pozi Pan Head Screws?

Imperial Pozi pan head screws are machine screws featuring a rounded, low-profile head with a Pozi drive recess, designed for enhanced torque transfer and reduced cam-out compared to traditional Phillips heads. 

These screws are manufactured to imperial (inch-based) thread standards, making them suitable for legacy equipment, maintenance or builds using imperial fasteners. A typical example might be in aerospace restoration or vintage machinery assembly, where precise imperial sizing is essential.

How Imperial Pozi Pan Head Screws Work

These screws use a Pozi drive, which allows for better alignment and torque control. The pan head provides a broad bearing surface, ideal for distributing load without the need for washers in some applications. Commonly used in control panels, casings and assemblies where flush or countersunk fittings are not required, these screws combine functional design with standardised imperial dimensions.

Materials Imperial Pozi Pan Head Screws Are Made From

Accu’s imperial Pozi pan head screws in this range are offered in carbon steel 4.8. This material is ideal for general-purpose fastening in engineering applications where high tensile strength is not critical. The screws are available with the following finishes:

• Bright Zinc Plating: Provides corrosion resistance in indoor environments and light-duty applications.
• Black Oxide: Offers minimal corrosion protection but enhances aesthetics and reduces glare, ideal for internal or low-visibility applications.

Sizes and Types of Imperial Pozi Pan Head Screws Available

A wide selection of thread sizes and lengths is available to suit varying engineering requirements:

• Thread Sizes: From 2-56 UNC to 1/4-20 UNC
• Lengths: Ranging from 1/8" to 1"
• Pozi Drive Sizes: PZ1 and PZ2

FAQs

Q: Why use imperial screws instead of metric?

A: Imperial screws are often required for compatibility with legacy systems, regional standards or specific industries such as aerospace and defence in the US and UK.

Q: Are these screws suitable for outdoor use?

A: Bright zinc plated versions offer some corrosion resistance but are not ideal for prolonged outdoor exposure. For outdoor or marine environments, stainless steel screws would be more suitable.
