Running out of the right screw size mid-project is a frustrating and avoidable problem. This 440-piece assortment solves it by combining two of the most-used head styles — hex washer and Phillips round head — across six common #8 lengths, all in one organized storage kit.
Every screw is machined from 410 stainless steel, a high-density alloy that outperforms standard stainless in hardness, stability, and corrosion resistance. Lengths run from 1/2" to 1-1/2", covering the full range of light-gauge sheet metal, wood, and panel fastening tasks. Package weight is approximately 900 g (1.98 lb).
Whether you're securing wood furniture, assembling electronic enclosures, maintaining HVAC ductwork, or fastening metal panels in an industrial setting, this dual-head assortment gives you the right fastener for the job without a separate trip to the hardware store.

For most sheet metal and wood applications, no pilot hole is required — the sharp self-tapping point cuts its own thread. For harder metals or thicker gauges, a small pilot hole may improve installation quality and reduce the risk of splitting.
The hex washer head is driven with a nut driver or socket and provides a wider bearing surface for higher clamping load and stability — ideal for structural or high-torque applications. The Phillips round head is driven with a standard Phillips bit and is faster to install, making it better suited for lighter-duty or high-volume fastening tasks.
410 stainless steel is a martensitic alloy with higher hardness and density than the more common 304 stainless steel. This makes it more resistant to deformation under torque and better suited for self-tapping applications where the screw must cut its own thread. It also offers good corrosion resistance in most environments.
Yes. 410 stainless steel resists rust and corrosion in most outdoor environments including high-humidity and temperature-variable conditions. For highly corrosive marine or coastal environments, 316 stainless steel is generally recommended for long-term exposure.
The kit contains 440 pieces total: Phillips Round Head (60+60+40+30+20+20 = 230 Pcs) and Hex Washer Head (50+50+40+30+20+20 = 210 Pcs) across all six lengths. See the What's in the Box table above for the full breakdown.
For the hex washer head: a 5/16" nut driver or socket with a power drill or impact driver. For the Phillips round head: a Phillips #2 bit with a standard power drill or cordless screwdriver. Both are compatible with common power tools.
The screws are sorted by size and head type into labeled compartments within a durable storage box. A size reference chart is attached to the box so you can identify each compartment at a glance without needing to measure individual screws.
