400 black self tapping screws in 9 metric sizes (M3–M5, 10–25 mm), black zinc-plated carbon steel. These washer head self tapping screws combine an integrated washer head with a Phillips drive — pressure spreads evenly and the head will not pull through plastic or thin panels.

Sorted in a clear 9-compartment case, this self tapping screw kit suits automotive trim, sheet metal, plastic components and DIY repairs. In stock; OEM private label, custom label, packaging and in-box assortment available.
Stop digging through jars for the right fastener. This 400-piece set of black self tapping screws puts nine of the most useful metric sizes — M3, M3.5, M4 and M5, from 10 mm to 25 mm — into one clear case you can read at a glance. Every screw is black zinc-plated carbon steel with an integrated washer head and Phillips drive: it starts fast, holds hard, and leaves a uniform black finish on the finished job.

Why Washer Head Self Tapping Screws Beat Ordinary Tapping Screws
The integrated washer is the whole point. A plain pan head concentrates load on a small circle; a washer head self tapping screw spreads that load across a wider flange, so the head will not sink into plastic housings, thin sheet-metal panels or soft trim — and you never have to add a separate washer that can drop into the machine you are repairing. That single detail is why these washer head self tapping screws hold better than an ordinary pan head screw of the same size, and why panel shops specify them for trim and enclosure work.
Pair that flange with a coarse self-tapping thread and a sharp gimlet point, and these black self tapping screws cut their own mating thread as they go. In wood and soft plastic you usually skip the pilot hole entirely.
One honest caveat from the workshop: a gimlet point is not a drill point. If you are working harder sheet metal, near an edge, or using the smallest diameters, drill a pilot hole first and always match the screw size to your material.
Key Features
Every one of these black self tapping screws shares the same six traits.
Integrated washer head (flange) — larger bearing surface, even clamping pressure, no pull-through on soft panels and no separate washer to lose.
Phillips drive — the standard cross recess, so any Phillips screwdriver or power bit in your box already fits. Anti-cam-out geometry keeps the bit seated under torque.
Coarse self-tapping thread — deep threads cut their own path and give strong holding power and high withdrawal resistance in wood, plastic and light-gauge metal.
Sharp gimlet point — starts quickly and locates accurately, which is why most jobs need no pre-drilling.
Black zinc-plated carbon steel — carbon steel for strength and hardness; black zinc plating for corrosion resistance and a clean, uniform black finish that suits automotive and enclosure work.
Retail-ready organization — 9 separate compartments, a clear body for instant size identification, and a compact footprint that fits a toolbox, workshop shelf or vehicle.

Where to Use Them — Automotive Trim, Sheet Metal, Plastic, Workshop
Automotive trim — securing selected trim panels, guards and non-structural accessories where the screw must sit flush to the surrounding surface.
Sheet metal — light-gauge panels, brackets and enclosures; drill a pilot hole on harder gauges and near edges.
Plastic components — housings, covers and general repair work, where the washer head prevents the classic cracked-boss pull-through.
DIY and workshop — garages, toolboxes and maintenance teams that want 400 black self tapping screws on hand instead of a trip to the hardware store.

FAQ
What does "washer head" mean? The head has a washer built into it (a flange). It creates a larger bearing surface and spreads clamping pressure evenly, which stops the head pulling through plastic or thin panels — with no separate washer to fit.
What sizes are in this 400-piece set? Nine metric sizes: M3 × 12 (60), M3 × 20 (60), M3.5 × 12 (40), M3.5 × 16 (50), M3.5 × 25 (40), M4 × 10 (40), M4 × 12 (50), M4 × 16 (30) and M5 × 12 (30).
Do I need a pilot hole? Usually not in wood or soft plastic — the sharp gimlet point starts fastening quickly. For harder sheet metal, small diameters or work near an edge, drill a pilot hole first.
Will they rust? These are carbon steel with black zinc plating for corrosion resistance and a uniform black finish. For outdoor, high-humidity or marine use, ask us about stainless steel or alternative finishes.
Are these black self tapping screws available in stock, and can we customize them? Yes — this self tapping screw kit is in stock and ready to ship, 24 boxes per carton. OEM / private label is available: custom lid label, custom packaging, custom in-box assortment and alternative surface treatments.
Are these washer head self tapping screws suitable for plastic? Yes — plastic housings and covers are their strongest use case. The integrated flange spreads load across a wider area, which is what stops the cracked-boss pull-through you get with a plain pan head. Pick the smallest diameter that still carries your load.
Can we buy black self tapping screws under our own brand? Yes. Send us your logo and channel requirements and we will quote a branded self tapping screw kit — custom lid label, custom packaging, custom in-box assortment and alternative finishes.
Is a gimlet point the same as a drill point? No. This screw has a sharp gimlet point that cuts threads in wood, plastic and light-gauge metal. A drill point (self-drilling) screw is a different product — tell us if you need that instead.
Whether you run an automotive trim shop, a metal enclosure line, a plastics assembly bench or just a well-used garage bench, 400 black self tapping screws in nine sorted sizes mean the right fastener is always within reach.
