The Spoon Point tip is different from your typical #2, #3, or #5 drill point. It’s got a shorter, more rounded flute—purpose-built for certain jobs where standard tips tend to overdo it.
A. Spoon Point – What It’s Really Made For
Fixing profiled metal sheets to timber: This is the sweet spot. The spoon shape stops the screw from drilling too deep too fast, which means no stripped holes and no torn-up wood fibers underneath. Perfect for timber purlins.
Thin metal cladding to light steel: When you’re working with thin-gauge steel, a regular aggressive drill point can chew right through it. The spoon point gives you a cleaner, more controlled hole.
B. Other Common Jobs This Screw Handles with Ease
Metal roofing and siding: This is the classic use case. Drills through corrugated sheeting and locks into steel frames underneath. The EPDM washer squishes down to form a proper waterproof seal—rated IP68, so rain doesn’t stand a chance.
HVAC and ductwork: Great for fixing metal ducting and securing air handling units without pre-drilling.
Solar panel mounts: Fully exposed to weather, needs good corrosion resistance and vibration damping. This setup delivers.
Metal-to-metal and metal-to-wood: Handles steel up to about 2.5mm thick without needing a pilot hole, plus timber framing jobs.
Truck bodies, boat hatches, marine interiors: Where you need a solid fix but don’t want to splash out on stainless steel. Zinc plating gives decent rust protection at a friendlier price.
Making a Spoon Point tip isn’t the same as rolling a standard thread. It needs precision grinding. Here’s the full 8-stage process, based on verified 12-station production lines from certified fastener manufacturers:
| Stage | Process | What Happens Here – Spoon Point Specifics |
|---|---|---|
| 1 | Wire Drawing | Starts as carbon steel rod—usually 1022A, 10B21, or SCM410. Gets pulled down to the exact diameter needed. |
| 2 | Cold Forging | The hex head and flange are slammed into shape at room temperature. Flange is usually about 1.5 times wider than the head to spread the load. |
| 3 | Point Grinding (This Is the Key Step) | Spoon Point geometry gets ground in. Short concave flute, typically 25° to 30°. This is what stops the screw from “hogging”—biting in too fast and blowing out the hole. |
| 4 | Thread Rolling | Screw body gets squeezed between high-speed dies to roll the thread profile. Follows ISO 1478 or DIN 7504. |
| 5 | Heat Treatment | Case hardening. Surface gets toughened up to handle drilling torque, but the core stays softer so the screw doesn’t snap. SCM410 grades are usually tempered to 32–39 HRC. |
| 6 | Surface Finishing | Zinc plating goes on via electroplating per ISO 4042. Not Dacromet, not paint—just solid zinc. Usually gives about 100 to 200 hours of salt spray resistance. |
| 7 | EPDM Bonding | Washer gets bonded to the flange using silane primer and UV curing. Compression ratio is tuned to around 40%—stays springy under load without going flat. |
| 8 | Screening & Packaging | Every screw gets optically scanned for tip geometry and washer presence. Then packed with VCI anti-rust paper so they don’t sweat in transit. |
Good news: plenty of suppliers will give you free samples.
Reality check: you’re still paying for shipping.
That’s pretty much standard across the industry. Here’s who does what:
| Supplier | Spoon Point? | Sample Policy | Who Pays Shipping? | MOQ |
|---|---|---|---|---|
| King Point Enterprise | ✅ Yes (explicit) | Not listed on site—best to ask. | Ask when inquiring | Ask when inquiring |
| Jiaxing Tuyue | ✅ Yes (explicit) | “Request for Quotation” – samples likely available. | Ask when inquiring | Ask when inquiring |
| Haiyan Jinrun | ⚠️ Hex/EPDM only | Free samples for standard sizes. | You cover courier | 1,000,000 pcs |
| Hailiang Fastener | ⚠️ Hex/EPDM only | Free stock samples. Custom ones charged, refundable with bulk order. | You pay shipping | 50 pcs |
| YHeng Hardware | ⚠️ Hex/Bi-Metal | Free 50-piece sample pack. | You pay shipping | 20,000 units |
| Hebei Shijing Changtian | ⚠️ Hex/Zinc only | Not clearly stated. | Ask when inquiring | 100 pcs |
How to Ask for Free Samples the Right Way:
Say “Spoon Point” explicitly. If you’re emailing King Point or Jiaxing Tuyue, don’t just ask for self-drilling screws—spell it out: “We need the Spoon Point tip, not the standard #2 drill point.”
Make shipping easy for them. Say this:
“We’d appreciate free samples for testing. We can provide a DHL/FedEx/UPS account number to collect the shipment.”
