Self-tapping screw for magnesite board mounting

 

Self-tapping screw for magnesite board mounting to wooden profile system

Peculiarities: Countersunk head
Anticorrosive coat
Special screw thread with angle 50°
Single thread
Cross slot: (PHILIPS)
Screwdriver bit: РН2
Surface treatment: Zinc plating (yellow colour/white colour) 3 micrometer (micron)
Material: Cemented steel
Type of mounting: straight-through joint
Base: Wooden profile system, flat bases from wooden sheets (OSB, wood chipboard, veneer and others), in some cases – metal profile not more than 0,5 mm
Fixed element: Magnesite board with not more than 15 mm of thickness
Advantages: – Countersunk head allows fixing of a magnesite board without preliminary spotfacing of places of screw fixation;- Anticorrosive coat prevents the formation of rust under the influence of moisture and worsening of fixation points of self-tapping screws in the process of time.

Self-tapping screw for magnesite board mounting to metal profile system

 

Peculiarities: Countersunk head with improved spotfacing
Strengthened drill
Anticorrosive coat
Max.thickness of drilling: Not more than 3 mm
Cross slot: (PHILIPS); Screwdriver bit РН2
Surface treatment: Zinc plating (yellow colour/white colour) 3 micrometer (micron)
Material: Cemented steel
Standard: DIN 7504 P
Type of mounting: straight-through, without preliminary drilling
Base: Metal profile, thickness 2mm
