The pan head design provides a broad, flat surface for secure fastening, while the cross recessed Phillips drive ensures ease of installation and minimizes cam-out during tightening.

Material: PEI Ultem

Features: Cross Recessed Phillips drive

Cross Recessed Phillips drive:

Enhanced Grip and Torque Transmission: The cross recessed Phillips drive allows for better engagement with the screwdriver, providing a secure grip that enhances torque transmission and reduces the risk of slipping or stripping the screw head.

Reduced Cam-Out: The Phillips drive design helps prevent cam-out (the tendency for the screwdriver to slip out of the screw head), which reduces damage to the screw and surrounding materials, ensuring a cleaner and more precise fastening process.

Manufactured in PEI Ultem:

High Mechanical Strength: PEI Ultem is known for its exceptional mechanical strength, allowing these screws to withstand significant loads and stress without deforming or breaking. This makes them ideal for applications requiring robust and reliable fasteners.

Thermal Stability: PEI Ultem maintains its mechanical properties at high temperatures, often up to 200°C (392°F). This makes the screws suitable for use in environments with extreme heat, such as in aerospace, automotive, and industrial machinery.

Chemical Resistance: PEI Ultem offers excellent resistance to a wide range of chemicals, including acids, bases, and solvents. This property ensures that the screws perform reliably in corrosive environments, extending their service life and reducing maintenance needs.

Flame Retardancy: PEI Ultem is inherently flame-retardant, providing added safety in applications where fire resistance is crucial. This characteristic is particularly valuable in industries with stringent fire safety requirements, such as electronics and aerospace.

Electrical Insulation: The material acts as an excellent electrical insulator, making these screws suitable for use in electronic and electrical applications where preventing conductivity is important.

Low Outgassing: PEI Ultem has low outgassing properties, which is essential for maintaining clean environments in sensitive applications like semiconductor manufacturing and cleanroom settings.

Corrosion Resistance: Unlike metal screws, PEI Ultem screws do not corrode, making them ideal for use in moist or humid environments. This ensures long-term durability and reliability.

Lightweight: Despite their strength, PEI Ultem screws are lightweight, which is beneficial in applications where weight reduction is important, such as in aerospace and automotive industries.

Precision and Consistency: PEI Ultem can be precisely molded, ensuring high-quality, consistent performance of the screws. This precision is crucial for high-accuracy applications and assemblies.

Biocompatibility: PEI Ultem is biocompatible, making these screws suitable for medical and healthcare applications where safety and compatibility with biological systems are required.
