Engineered for Woodworkers Who Refuse to Tolerate Stripped Heads or 'Spinners'
Every detail of the Cosari MicroGrip M2 assortment is built to eliminate the frustrations of cheap big-box blister packs and messy uncalibrated import kits.
8 Calibrated Metric Lengths (4mm–20mm)
Includes 100 pieces each of M2×4mm, 5mm, 6mm, 8mm, 10mm, 12mm, 16mm, and 20mm—so you never poke a screw through a thin lid or come up short on cabinet trim.
Deep-Cut Zero-Wobble Phillips Slots
Precision-forged cross recesses seat your #0 or #1 driver tip squarely on the first try, delivering clean hand torque without rounding out or scarring brass hardware.
28° Self-Tapping Point & Deep Threads
Needle-sharp tips and high-crest spiral wood threads bite immediately into softwood without pilot holes and pull hardware tight without turning into 'spinners.'
90° Dead-Flush Countersunk Flat Head
Engineered with a true 90-degree flat-head taper that seats completely flush inside miniature butt hinges, clasps, and trim plates so lids close without binding.
Why Makers & Luthiers Switch to Cosari MicroGrip
1. Instant Self-Tapping Bite Without Splitting
Instead of blunt machine threads that chew up delicate grain, each M2 screw features a razor-sharp 28° point and coarse wood-biting flutes that pull straight down on the first turn.
2. Rock-Solid Bit Engagement Under Load
Hardened carbon steel with a bright nickel-silver finish prevents the Phillips cross-slot from deforming, keeping your #0 or #1 precision screwdriver locked straight from start to finish.
3. Factory-Flush Seating in Miniature Hardware
The 90° countersunk head tucks cleanly into small hinge leaves and wood countersinks, leaving a gleaming, snag-free silver finish that resists shop humidity and rust.

Big-box mini packs use soft zinc castings that twist apart in oak. Cosari heat-treats carbon steel and finishes it in bright nickel so slots stay crisp and shanks stay strong.
Spill-Proof 10-Grid Snap-Latch Organizer
Full-height baffle dividers meet the inside of the closed lid while dual front snap-latches lock tight—so your 4mm and 20mm screws never mix together in a tool drawer.
Save Over $215 vs. Retail 8-Packs
Buying 100 retail 8-packs at $2.48 each costs $248.00. Get all 800 calibrated M2 screws in a reusable workshop case for just $29.99 today.

Care & Safety
Always drive M2 micro screws using a properly fitted #0 or #1 precision Phillips hand screwdriver rather than a high-torque cordless impact driver.
In softwoods (pine, basswood, cedar), no pilot hole is required; when driving the 16mm and 20mm lengths into dense hardwoods (oak, hard maple, walnut), pre-drill a 1.5mm (1/16") pilot hole.

From Unlatching the Case to a Dead-Flush Finish in 30 Seconds
Swipe left for steps 2 and 3
1
Step 1: Unlatch & Pick Your Exact M2 Length
Pop open the dual front snap-latches on the 10-compartment translucent case and select the exact length (4mm to 20mm) required for your wood thickness.
2
Step 2: Seat on a #0 or #1 Precision Driver
Press your #0 or #1 Phillips precision tip into the deep cross-slot—where the screw holds straight without wobbling—and align the sharp self-tapping point with your mounting hole.
3
Step 3: Drive Smoothly Until 100% Flush
Turn smoothly by hand as the coarse threads pull the screw downward until the 90° flat head sits dead-flush with your hinge leaf or wood surface.

Are the length measurements taken from the top of the flat head to the tip?
Yes. Following international DIN/ISO standards for 90-degree countersunk flat-head wood screws, the stated length (4mm through 20mm) represents the total overall length from the top flush surface of the head to the self-tapping tip.
What size screwdriver bit fits these M2 screws best?
A #0 or #1 precision Phillips screwdriver fits the cross-recess tightly with zero wobble. Avoid using a large #2 drywall bit or a high-torque cordless impact driver.
Will the tiny 4mm and 5mm screws mix together inside the box during shipping?
No. The 10-compartment translucent polypropylene case is molded with full-height divider walls that meet the closed lid, secured by dual front snap-latches so each length stays in its dedicated bay.
Do I need to drill a pilot hole before driving them?
In softwoods such as pine, basswood, balsa, fir, and cedar, the 28-degree needle-sharp self-tapping point bites immediately without a pilot hole. When driving into dense hardwoods like oak, maple, or walnut—especially with the longer 16mm and 20mm lengths—we recommend pre-drilling a 1.5mm (1/16 inch) pilot hole.
How does the 30-Day Money-Back Guarantee work?
Put the Cosari MicroGrip kit on your workbench for 30 days and test the screws on your own projects. If you aren't thrilled with how cleanly they drive, how flush they sit, or how well the case stays organized, simply contact us for a full 100% refund.
