Screw with washer 6.3x90mm /Ø16mm self-drilling 6pcs/blister 900513 PRO M

The 6.3 x 90 mm screw from the PRO M brand is a self-drilling screw with a hexagonal head and an integrated flange (washer), complying with the DIN 7504K standard. It is designed for quick and secure fastening of metal structures and sheet metal elements without the need for pre-drilling holes.

The hexagonal head allows screwing with a wrench or HEX bit, and the integrated flange provides a larger contact area and even pressure distribution. The "drill" type tip pierces the material and cuts the thread at the same time, which makes installation easier and saves time. The screw is made of hardened carbon steel with a zinc-plated coating for corrosion protection, and there are also stainless steel (A2) options.

In some applications, especially roofing, the screw can be used with an additional EPDM (neoprene) washer, which provides a tight and watertight connection.

Purpose:

• Fastening metal structures and sheets without pre-drilling
• Installation of thin-walled metal elements, roof and facade panels
• Metal-to-metal and metal-to-wood connections
• Suitable for domestic and professional installation applications

Main advantages:

• Hexagonal head for strong and controlled screwdriving
