The best square tip screwdriver set depends on whether you need complete hand tools or replaceable bits for a driver. The LOZAGU and Narwhal five-piece sets cover sizes #0 through #4, while the Klein four-piece set offers color-coded handles. WORKPRO is the better choice for a compatible bit driver, and the four-piece SQ0–SQ3 set suits buyers who need its specified metric tip sizes.
| Set | Best For | What Stands Out |
|---|---|---|
| LOZAGU 5-Piece | A broad range of hand-tool sizes | Magnetic tips; #0–#4 |
| Narwhal 5-Piece | Quick size identification | Etched handle markings; #0–#4 |
| Klein Tools 85664 | Color-coded hand tools | Cushion-Grip handles; chrome-plated shafts |
| WORKPRO 10-Piece Bit Set | Use with a compatible bit driver | 1/4-inch hex shanks; storage box |
| SQ0–SQ3 Four-Piece Set | Buyers seeking specified metric sizes | Magnetic tips; CR-V steel bits |
LOZAGU Five-Piece Square Head Set
This set includes square tips in sizes #0, #1, #2, #3, and #4, making it a practical pick for buyers who want several common numbered sizes in individual hand tools. The tips are magnetic, and the shafts are made from heat-treated chrome vanadium steel. Its cushioned TPR handles are designed for grip and control.
Best for: Homeowners and repairers who want a broad #0–#4 selection without swapping bits in a driver. It was selected for its five-size range and magnetic tips. Limitation: The listing does not provide shaft lengths, so check tool dimensions if reach is important for your work.
Narwhal Five-Piece Robertson Set
The Narwhal set includes sizes #0 through #4, magnetic tips, chrome vanadium steel shafts, and soft ergonomic handles. Each tool has its size etched on the handle, which helps identify the right driver without sorting through unmarked tools.
Best for: Buyers who value fast size identification alongside a complete numbered set. Choose this over a less clearly marked set if tools are frequently shared or stored together. Limitation: The product details do not list shaft lengths or handle dimensions, so compare those measurements if you need a specific reach or grip size.
Klein Tools 85664 Square Recess Set
This four-piece set has square recess tips, round shanks, and color-coded handle ends for easier tool identification. Its heat-treated, chrome-plated shafts are described as corrosion resistant. Klein’s Cushion-Grip handles are designed to provide comfort and leverage for turning screws.
Best for: Buyers who prefer full-size hand screwdrivers with visible color coding and cushioned grips. It was selected as a distinct option from the five-piece #0–#4 sets. Limitation: The supplied product details do not state the individual tip sizes, so confirm that the set covers your screw sizes before purchasing.
WORKPRO Ten-Piece Square Drive Bit Set
Unlike the other picks, this is a bit set rather than a collection of complete hand screwdrivers. It includes square drive bits made from heat-treated S2 alloy steel, with 1/4-inch quick-change hex shanks and a storage box. The manufacturer also lists CNC-precision-machined tips, magnetic tips, and a manganese phosphate surface treatment.
Best for: Buyers who already have a compatible driver or bit holder and want replaceable bits for repeated use. The bit format and storage box make it a useful alternative to carrying several separate screwdrivers. Limitation: It requires a compatible tool with a 1/4-inch hex bit connection; it is not a standalone screwdriver set.
Four-Piece SQ0–SQ3 Square Set
This set specifies four sizes: SQ0 (2.0 mm), SQ1 (2.5 mm), SQ2 (3.0 mm), and SQ3 (3.5 mm). The screwdriver bits are made from chrome vanadium steel, the handles are transparent PVC, and magnetic tips help hold screws during handling.
Best for: Buyers whose work calls for the listed SQ0–SQ3 metric dimensions and who want individual hand tools. It was selected because its sizes are explicitly stated in millimeters. Limitation: It does not include SQ4, so choose a different set if that size is required.
Buying Guide: How To Choose A Square Tip Screwdriver Set
Do you need hand screwdrivers or driver bits?
Hand screwdrivers are ready to use as individual tools. A bit set is more compact when paired with a compatible driver, but it depends on that separate tool. The WORKPRO set has 1/4-inch hex shanks; check your driver or holder before choosing it. For standalone tools, compare the LOZAGU, Narwhal, Klein, and SQ0–SQ3 options.
Which square tip sizes should you look for?
Match the driver tip to the screw recess. A tip that is too small or too large may not seat properly. The LOZAGU and Narwhal listings specify #0 through #4, while the SQ0–SQ3 set gives both its labels and metric measurements. The Klein listing’s supplied details do not identify its individual sizes, so verify those before buying.
Do magnetic tips and handle markings matter?
Magnetic tips can help hold a screw on the driver during positioning. They are listed for the LOZAGU, Narwhal, WORKPRO, and SQ0–SQ3 sets. For finding the right tool quickly, the Narwhal set has etched size markings, while Klein uses color-coded handle ends.
What should you compare for comfort and storage?
Consider handle material and shape if you expect repeated hand use. LOZAGU lists cushioned TPR handles, Narwhal lists soft ergonomic handles, and Klein lists Cushion-Grip handles. For storage, WORKPRO includes a box. The available product details do not give exact screwdriver lengths for most sets, so check dimensions when access to recessed or narrow areas matters.
Frequently Asked Questions
What is a square tip screwdriver called?
It is commonly called a Robertson or square recess screwdriver. Its square-shaped tip fits a square recess in a screw head.
Are square drive bits the same as complete screwdrivers?
No. Bits need a compatible driver or bit holder, while complete screwdrivers have their own handles and shafts.
Which listed set includes sizes #0 through #4?
The LOZAGU and Narwhal five-piece sets both list square tips in sizes #0, #1, #2, #3, and #4.
Which set lists metric dimensions for its tips?
The four-piece SQ0–SQ3 set lists sizes from 2.0 mm through 3.5 mm.
Should I choose a magnetic square tip?
A magnetic tip can help hold a screw while positioning or removing it. Choose one if that feature is useful for your task, while still matching the tip size to the screw recess.
