Heat Resistance Temperature＊1	260℃

＊1：　This is the value for the resin material. The operating temperature of the product changes with performance conditions such as tightening torque.

Application

FPD production equipment / Semiconductor manufacturing equipment / Printed circuit board etching devices / Metallic surface treatment equipment and facilities / Chemical plants / Transformers / Electrical and electronic equipment / Hot water pumps / Chemical pumps

Characteristics

PEEK hex head bolts.
PEEK is a thermoplastic super engineering plastic superior in physical and chemical properties.
Excellent chemical resistance. It remains almost unaffected by chemicals other than concentrated sulfuric acid, concentrated nitric acid, and concentrated hydrofluoric acid.
With excellent heat resistance and water resistance, it retains strength at high temperatures.
It features outstanding resistance to wear, shock, and fatigue.
It also has high flame retardance which clears the UL 94 V-0 standard.
For the properties and precautions for use of plastic screws, see “Properties of Plastic Screws.”⇒Plastic Screws

Precautions for Use

Because a cumulative pitch difference is created when PEEK screws are manufactured, use these screws with nuts. If a nut is not used, use a 20 mm or less fit with female thread.
