Wera 851/4 BTZ BiTorsion Extra Tough Phillips Screwdriver Bits
The Wera 851/4 BTZ BiTorsion Extra Tough Phillips Screwdriver Bits represent professional-grade engineering designed to withstand the most demanding applications. These bits feature Wera's innovative dual-zone design, combining an elastic Torsion zone that diverts kinetic energy from peak loads with a softer BiTorsion zone that prevents the bit tip from twisting under extreme stress. This intelligent construction significantly extends service life whilst dramatically reducing the risk of breakage.
Manufactured to be tough and viscous, these bits are ideal for universal use across hard materials and challenging screwdriving tasks. The ¼" hexagon drive conforms to DIN ISO 1173-F 6.3 standards, ensuring compatibility with holders in Wera's connecting series 4. Available in sizes PH 1, PH 2, and PH 3, all in 50mm length.
Features and Benefits:
• BiTorsion zone absorbs peak loads to protect bit integrity
• Considerable reduction in breakage risk with significant service life increase
• Ductile and tough construction for hard materials
• ¼" hexagon drive compatible with standard holders
• Suitable for Phillips screws in professional applications
