Wera 05057710001 Phillips Insert Bit 2 Point 5/16 in

Product Description

The WERA 05057710001 is a standard Phillips screwdriver insert bit designed for use with 5/16 inch hex drive power tools and bit holders. Built to a 2 point (PH2) profile, this bit measures 1.25 inches in overall length and is engineered for ductile toughness and tough viscous performance - characteristics that help the bit resist cam-out and wear under repeated torque cycles. Weighing just 0.1 pounds, it is a compact, high-cycle accessory suited for production, service, and assembly work across multiple trades. Electricians, HVAC technicians, and general service professionals regularly reach for this format when driving Phillips fasteners in tight or speed-critical applications.

This insert bit fits any standard 5/16 inch hex bit holder or quick-change chuck. The PH2 drive point is the most common Phillips size encountered in electrical panels, HVAC equipment cabinets, junction boxes, and general equipment assembly. Its 1.25 inch OAL is the standard insert length, making it compatible with bit extenders, magnetic bit holders, and most cordless and pneumatic screwdriver chucks used in commercial and residential service work.

Key Features

• PH2 Phillips profile - most widely used Phillips drive point size in trade applications
• 5/16 inch hex shank fits standard bit holders and quick-change chucks
• 1.25 inch overall length - standard insert format for use with extenders and holders
• Ductile and tough construction resists cam-out and bit breakage under repeated use
• Tough viscous material treatment supports high-cycle performance in production and service environments
• Lightweight at 0.1 pounds - minimal added weight in a tool belt or pouch

Compatibility

Designed as a standard 5/16 inch hex insert bit for use with compatible bit holders, quick-change chucks, and bit extenders that accept the 5/16 inch hex drive format.

Installation Notes

Seat the bit fully into the hex drive holder or chuck before applying torque to prevent slippage or drive damage. Inspect the bit tip for wear or deformation before each use - a worn PH2 profile increases cam-out risk and can damage fastener heads. Replace the bit when tip geometry shows visible rounding. No special tools or codes apply to bit installation beyond standard tool-manufacturer guidance for bit holder engagement.
