Flat screws made of PTFE

We offer a wide range of products tailored to various purposes.

The PEEK small screw with a cross hole (PE-0000) is made from a highly heat-resistant (continuous use temperature of 240°C) crystalline resin that is flame-retardant, capable of continuous use in 200°C steam, has good radiation resistance, and does not dissolve in chemicals other than concentrated sulfuric acid, exhibiting very unique properties. Moreover, it is thermoplastic and can be processed using standard molding machines. For more details, please download the catalog.

The brass small screw "B-0000" is made from brass, also known by the old JIS symbol BSBMBD, which contains 35-45% zinc, making it suitable for high-temperature processing and excellent in machinability. It has been treated with nickel plating (Ni). It complies with RoHS standards. For more details, please download the catalog.

At Hiroseki Co., Ltd., we offer "metal rivets" made from aluminum, steel, and stainless steel, as well as "plastic rivets" made from nylon 66/46. We support our customers with a wide variety of products, small lots, and short delivery times. [Types] ■ Metal Rivets: Push Rivets, Drive Rivets ■ Plastic Rivets: Push Rivets, Fan Snap Rivets *For more details, please refer to the PDF document or feel free to contact us.

Plastic screws have high electrical resistance and excellent insulation properties. By using plastic screws with superior insulation, it is possible to prevent short circuits. ● Lightweight: Plastic screws are very lightweight, making them suitable for products and equipment where weight reduction is necessary. ● Electrical Insulation: Plastic screws have high electrical resistance and excellent insulation properties. By adopting plastic screws with superior insulation, it is possible to prevent short circuits. ● Strength: Screws made of high-strength materials like PPS and RENY offer greater strength, allowing for reduced screw diameter and fewer screws, leading to space-saving designs. ● Heat Resistance: Materials such as PPS, PEEK, and PTFE have heat resistance temperatures above 200°C, providing stable performance even under harsh temperature conditions. ● Thermal Insulation: Plastic screws have low thermal conductivity and excellent thermal insulation properties. They can prevent localized condensation due to thermal bridges. Efficient thermal management can be achieved in the design of equipment and devices where temperature control is critical. ● Corrosion Resistance: Plastic screws do not rust or corrode, providing excellent resistance to moisture and chemicals.
