WX-58T is a carbon steel self-drilling screw with a hardened drill point and Ruspert coating for fixing into light steel substrates between 0.7mm and 2.0mm. It is designed for securing insulation boards, sheathing boards, and render boards to light steel framing systems. Suitable for applications requiring controlled installation torque and defined pull-out performance.
WX-58T is a 5.8mm diameter self-drilling carbon steel screw featuring a hardened drill point (No.2) and Ruspert coating. The product is intended for fixing insulation to sheathing boards and attaching sheathing or render boards to light steel framing systems with substrate thicknesses from 0.7mm to 2.0mm. The data sheet specifies torsional strength, hardness ranges, installation criteria, and pull-out values obtained from testing carried out in Grade S235 steel.
Product Features and Characteristics
The screw incorporates a hardened drill point suitable for steel thicknesses of 0.7–2.0mm. Surface hardness is stated as minimum 560HV0.3, while the core hardness ranges from 270HV5 to 425HV5. Torsional strength is declared as 9.8Nm. Drive type is TX25. These physical characteristics provide defined drilling performance when used with compatible steel framing materials.
The technical sheet includes tensile strength of 14.08kN and shear strength of 8.27kN, supported by testing completed in the Rawlplug Technical Department using S235 steel sections.
Intended Applications
The screw is intended for the installation of:
-
Insulation to sheathing board and light steel frame
-
Render and sheathing boards to light steel framing systems
The installation requirements indicate its use where controlled screw alignment and suitable drilling speed are necessary.
Installation Guidance
The data sheet provides installation guidance specifying:
-
The screw must be driven at 90° to the substrate.
-
The correct drive bit must be used.
-
The lowest torque setting should be selected to start installation.
-
A cordless impact driver may be used.
-
A screw gun operating at 1000–1800RPM with regulated torque is recommended.
Minimum spacing is 30mm and minimum edge distance is 10mm. Substrate thickness must be within 0.7–2.0mm. These requirements support achieving the pull-out values listed in testing.
Performance Data
Pull-out performance values are supplied for various steel thicknesses ranging from 0.7mm to 2.0mm. Values are presented as average ultimate, characteristic, design, and recommended resistances. All testing was carried out in Grade S235 steel.
Further mechanical performance data includes torque strength, tensile strength, and shear strength, defined in the technical table on page 1 of the data sheet.
Additional Product Data
A range of product codes and lengths from 40mm to 300mm is shown in the data sheet. Associated packaging quantities and weights for each code are also provided. These details allow selection based on required fixing depth and packaging preferences.
