Description

Thread-forming RXS sheet metal screw with pan head in A2 / AISI 304 stainless steel is built to resist corrosion and maintain its strength for a long time. The pan head provides a neat finish and a good contact surface, while the thread-forming tip allows the screw to form its own thread in the material. This makes it perfect for fast and secure installation in pre-drilled or punched holes in thinner sheet metal.

AREA OF USE

Perfect for fastening sheet metal, fittings, sheet materials, and equipment in construction projects, workshops, furniture production, vehicles, and light industry. The thread-forming function provides a stable and vibration-resistant connection without the need for nuts or extra fittings. Easy to install with a cross-head screwdriver (PH) and requires minimal maintenance even during continuous operation.

FREQUENTLY ASKED QUESTIONS (FAQ)

What characterizes an RXS thread-forming sheet metal screw with pan head?

An RXS sheet metal screw (according to DIN 7981 / ISO 7049) is a thread-forming screw designed for efficient joining of sheet metal and thin-walled materials:

  • Thread-forming tip and thread: The screw presses and forms its own mating thread in the underlying material as it is screwed in. This provides a very tight, strong, and vibration-resistant fastening.

  • Pan head (RXS): The rounded head provides an aesthetically pleasing finish without sharp edges and has a flat underside contact surface that distributes clamping force effectively against the sheet metal.

  • Time-saving assembly: Eliminates the need for tapping and makes installation quick and smooth in pre-drilled or punched holes in thinner metal and plastic.

Why is A2 (AISI 304) stainless steel the right choice for sheet metal screws?

A2 steel (1.4301 / AISI 304) provides reliable corrosion protection in most outdoor and industrial environments:

  • High corrosion resistance outdoors: Withstands rain, moisture, snow, and changing weather conditions without rusting or losing strength.

  • Neat and clean result: Does not cause unsightly rust streaks on facade cladding, sheet metal fittings, outdoor lighting, or vehicles.

  • Wide application: Ideal for sheet metal work, building metalwork, ventilation, trailers, and electrical cabinets where moisture exposure occurs.

What should be kept in mind when installing stainless A2 sheet metal screws?

  1. Pre-drilling required in sheet metal: Unlike self-drilling screws (with drill point), the RXS sheet metal screw has a pointed thread-forming tip. Holes must therefore be pre-drilled or punched in the sheet metal before the screw is driven in. Match the drill diameter carefully to the screw's core diameter and the thickness of the sheet metal.

  2. Avoid overtightening in thin sheet metal: Adjust the torque on the screwdriver so that the threads in the sheet metal are not stripped (slipping) when the head reaches the surface.

  3. Consider material hardness: Stainless A2 screws are intended for installation in softer metals such as aluminum, brass, plastic, or thinner stainless steel sheet where holes have already been punched/drilled. When installing in harder steel sheet, the tip may deform if the hole dimension is not precisely matched.
