Self-tapping screw DIN 7982 3,9x19 A2 (PH2)

On this page the dimensions are given in the title. Below you can read what to look for when choosing, so you know whether this screw suits your application.

For which applications do you choose a D.7982C self-tapping screw?

Self-tapping screws are used to fasten thin sheet materials to each other or to a substrate. Think of metal profiles, cladding and components in installation or renovation work. Which material and sheet thickness the screw can handle depends on the version. Always check this beforehand for your own application.

What does A2 stainless steel mean for your choice?

A2 is a widely used stainless steel grade that resists rust well indoors and in most outdoor applications. In very aggressive environments, such as seawater or air with a high chlorine content, a heavier-duty stainless steel grade is often chosen. If you are unsure, ask for advice before you order.

Size and cross head: what to look for

The length of 19 mm must match the thickness of the parts to be joined. The screw must get sufficient grip in the underlying material. For the PH2 cross head you use a PH2 bit. A bit of a different size or shape, for example PZ, can damage the head. Preferably use a matching bit and even pressure, so the head does not strip.

Frequently asked questions

Which bit do I need for this self-tapping screw?

The screw has a PH2 cross head, so you use a PH2 bit. A matching bit prevents damage to the head.

Do I need to pre-drill with a self-tapping screw?

With thin materials, pre-drilling is often not necessary, because the screw forms its own thread. With thicker or harder material, a pilot hole can help. Check this for your application.

Is A2 stainless steel suitable for outdoor use?

A2 resists rust in many outdoor applications. For environments with salt or aggressive substances, a heavier-duty stainless steel grade is often required.
