Protorq 10-Piece Imperial Hex Impact Bit Set, 2 in. Length

Imperial Hex Impact Bits for Maximum Durability and Torque Transfer

When adding impact driver bits to the TSO lineup, our engineering team evaluated a wide range of hex driver sets for fit, durability, and real-world performance. Protorq consistently ranked at the top for quality and value, earning its place as a brand we’re confident putting in your shop.

This imperial hex square end impact bit set is designed for applications where maximum strength, durability, and fastener engagement are critical.

Why Square End Hex Bits

Square end (traditional) hex bits provide full surface contact inside the fastener, making them the preferred choice for high-torque applications and repeated fastening cycles. Compared to ball end tips, square ends offer improved durability, reduced wear, and better resistance to rounding under load.

For assembly, installation, and maintenance tasks where alignment is straight and access is not restricted, square end hex bits deliver the most reliable and long-lasting performance.

Built for Impact Use

Each bit is made from S2-H steel and impact-rated for use with impact drivers and drill drivers. This balance of hardness and toughness allows the bits to withstand repeated torsional shock without cracking, chipping, or deforming—especially important in square end hex bits that see higher contact stress during high-torque driving.

A manganese phosphate surface treatment improves wear resistance, reduces friction during use, and helps protect against corrosion. Laser-engraved size markings make identification quick and easy, even after extended use.
