HitScrews 5-in-1 Reversible Magnetic Nut Driver Bit, Impact Double-Ended Flip Socket for H1/4 H5/16 H8 H10 & PH2, S2 Alloy Steel, 1/4" Hex Shank for Metal Roofing, HVAC & Sheet Metal

Availability set by the retailer

The HitScrews 5-in-1 Reversible Magnetic Nut Driver Bit replaces five separate tools with one compact, impact-rated bit that covers PH2, H1/4", H5/16", H8, and H10 sizes. The innovative double-ended flip design lets you quickly switch between sizes without changing bits, while the integrated PH2 power bit handles common screws and the hex sockets drive bolts with ease — making it ideal for metal roofing, gutter installation, HVAC work, and sheet-metal fastening. A built-in ball-locking mechanism keeps the bit firmly seated during high-torque driving, preventing wobble and accidental drop-outs for a stable, controlled experience even at high speed with an impact driver. Forged from professional-grade S2 alloy steel for exceptional hardness, torque resistance, and long service life, the black manganese phosphate coating adds superior corrosion resistance for demanding outdoor environments. An embedded high-power magnetic core securely holds hex-head bolts and self-tapping screws, and CNC-machined tips ensure a precise fit that reduces cam-out and protects fastener heads during one-handed operation on eaves and roofs. The 1/4" hex shank works seamlessly with impact drivers, power drills, and screwdrivers. Brand: HitScrews; Material: S2 Alloy Steel; Head Style: Hex; Color: H5/16 & H1/4; Size: 5 in 1 (5/16 & 1/4); Shank: 1/4" Hex; Rating: 4.6 out of 5 stars (7 ratings); ASIN: B0GGS124KT.

Choosing Bits & Drilling

How do I choose driver bits?

Match the bit tip to the fastener recess exactly — Phillips, Torx, square, or hex — because a loose fit strips the fastener. For impact drivers, use impact-rated bits (typically S2 steel) that withstand concussive loads; standard bits can snap. A magnetic bit holder keeps fasteners in place for one-handed driving.

When do I need a step drill bit?

Step bits drill a range of hole sizes in thin material like sheet metal, electrical boxes, and plastic, deburring as they cut. They are not a substitute for twist bits in thick steel, where a dedicated drill bit is more efficient. Choose a step range that covers the hole sizes you actually need.
