Detail & Specs
M20X2.5 Socket Head Cap Screw - A2-70 Stainless ISO 4762
Socket head bolts are great for limited space installation areas. An allen wrench is used to install these screws, allowing access into tight locations where a traditional external hex drive bolt would not fit.
Partially threaded socket cap bolts have an unthreaded length under the head that is stronger than the threaded portion of the bolt. The unthreaded / threaded length proportions vary by diameter.
Fully threaded socket cap screws are meant to engage the entire length with a tapped hole. The head style may be smooth or knurled. These bolts can be used with many different styles of locking and non-locking nuts, tightly clamping together whatever the cap screw is being used to secure.
Material: A2 / SAE Type 303
A2 / 303 / 18-8 Stainless Steel fasteners are best for general use applications. They have good chemical resistance and are suitable for use in damp environments, popular across a wide range of industries: automotive, agriculture, medical, food and beverage processing, clean energy, etc.
Per DIN EN ISO 3506: A2-70 austenitic stainless steel specifically refers to a tensile strength of at least 700 N/mm2.
