Frequently asked questions about the ШУРУП ПО ДЕРЕВУ 8,0x70 WAF/CE TX40/A4/C5/ 4tk
What is ШУРУП ПО ДЕРЕВУ 8,0x70 WAF/CE TX40/A4/C5/ 4tk?
ШУРУП ПО ДЕРЕВУ 8,0x70 WAF/CE TX40/A4/C5/ 4tk is a 70 mm long, 8 mm diameter stainless steel A4 wood fixing screw with 50 mm partial thread, WAF/CE head, TX40 drive and corrosion class C5, designed for external timber applications.
What materials is this screw suitable for?
ШУРУП ПО ДЕРЕВУ 8,0x70 WAF/CE TX40/A4/C5/ 4tk is intended for fastening into wood; its A4 stainless steel and C5 corrosion class make it suitable for external and damp conditions.
What is the thread length and how does it affect installation?
The ШУРУП ПО ДЕРЕВУ 8,0x70 has a partial thread with 50 mm of thread on a 70 mm screw. This provides strong holding in timber while reducing compression between joined parts.
What head and drive type does the screw have?
The screw has a WAF/CE installation head with a 17 mm head diameter and a TX40 drive, providing reliable torque transfer during driving.
Is this screw suitable for exterior structures and marine climates?
Yes. The A4 stainless steel material and C5 corrosion class make the ШУРУП ПО ДЕРЕВУ 8,0x70 suitable for external structures and aggressive environments, including coastal conditions.
What is the recommended rotation speed when driving the screw?
Recommended speeds for the ШУРУП ПО ДЕРЕВУ 8,0x70 are 400–1200 rpm depending on tool and timber hardness; start at lower rpm and adjust as needed.
What is the core diameter of the screw and why does it matter?
The core diameter is 5.3 mm. Core diameter affects the screw's torsional strength and indicates whether pre-drilling is needed in dense woods.
Do I need to pre-drill for this screw in hard wood?
Pre-drilling is recommended in dense hardwoods. Use a drill bit matching the 5.3 mm core diameter to reduce the risk of wood splitting.
What is the external/thread and head diameter and how does that affect fixing to facades or plates?
Thread external diameter is 8 mm and head diameter is 17 mm; the large head provides a good bearing area for facades and fixing plates.
What thread type does the screw have and what is partial thread suitable for?
The screw has a partial thread (osakeere). Partial thread is suitable for clamping joined parts tightly, offering good withdrawal resistance while minimizing deformation.
