M4-1.79 x 20mm Thread Forming Screws for Plastics 30 Degree Thread Flank/Six-Lobe/Round Washer Head/Steel/Zinc (600 pcs)

M4-1.79 x 20mm Thread Forming Screws for Plastics are specifically designed to securely fasten plastic materials. Made from high-quality steel and coated with zinc, these screws are durable and resistant to corrosion, ensuring a long-lasting hold. With a 30-degree thread flank, these screws provide a strong grip on plastic surfaces, preventing them from loosening over time. The thread-forming design allows for easy installation, as it creates its own threads in the plastic material, eliminating the need for pre-tapping. The six-lobe drive design ensures optimal torque transfer, reducing the risk of stripping or damaging the screw head. This design also provides a more secure fastening, preventing slippage during installation. Featuring a round washer head, these screws offer a large surface area for distributing the load and minimizing the risk of damage to the plastic material. This head design also provides a clean and professional appearance once installed. With a size of M4-1.79 x 20mm, these screws are suitable for a variety of plastic applications, including electronics, automotive, and consumer products. Their versatility and reliability make them an excellent choice for both professional and DIY projects. In summary, the M4-1.79 x 20mm Thread Forming Screws for Plastics combine quality materials, a secure thread flank, a six-lobe drive, a round washer head, and a corrosion-resistant coating to provide a durable and reliable fastening solution for plastic materials.

• Self-tapping fasteners that can be used to directly attach thermoplastics. They have a narrow 30° thread profile that reduces radial expansion and stress in the boss, allowing for thinner bosses. This can reduce cycling times and material usage. PT screws also have a high load-carrying capacity due to their large thread-bearing depth
