It measures 1 inch in overall length and is rated for impact tool use, making it suitable for high-torque fastening applications where standard bits may fail. Constructed from steel, this bit is built to withstand the torsional stress of impact drivers and electric screwdrivers. It fits M4 cap screws using a standard hex fastener profile without a ball end. Electricians, HVAC technicians, plumbers, and general trade professionals keep these bits on hand for panel work, equipment assembly, and fixture installation.\u003c\/p\u003e\n\u003cp\u003eThis insert bit is intended for use in residential and commercial trade applications wherever a 1\/4 inch hex drive impact driver or manual screwdriver handle is in use. The M4 metric sizing makes it well suited for equipment fasteners commonly found in HVAC units, electrical enclosures, and plumbing fixtures. It is sold individually by piece, with a package quantity of 10 units per order, making it practical for stocking tool bags or service vans.\u003c\/p\u003e\n\u003ch4\u003eKey Features\u003c\/h4\u003e\n\u003cul\u003e\n  \u003cli\u003eImpact rated for use with pneumatic and electric impact drivers\u003c\/li\u003e\n  \u003cli\u003e1\/4 inch hex drive fits standard quick-change bit holders\u003c\/li\u003e\n  \u003cli\u003e1 inch overall length suits confined fastening locations\u003c\/li\u003e\n  \u003cli\u003eM4 metric hex profile for cap screw applications\u003c\/li\u003e\n  \u003cli\u003eStandard hex (no ball end) for full torque engagement\u003c\/li\u003e\n  \u003cli\u003eSteel construction for durability under repeated use\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eCompatibility\u003c\/h4\u003e\n\u003cp\u003eDesigned for use with any 1\/4 inch hex drive tool holder, including impact drivers, bit extension bars, and screwdriver handles that accept standard insert bits.\u003c\/p\u003e\n\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\n\u003cp\u003eInsert bits should be seated fully into the bit holder before applying torque to prevent cam-out or bit ejection. When using with an impact driver, confirm the bit is rated for impact use before operation. Replace bits showing visible wear, rounding, or cracking, as damaged bits can strip fastener heads and create rework.
