The related product list helps you compare China 1-1/4 Self Drilling Screws Manufacturer, Factory & Suppliers by actual product direction rather than keyword wording alone. Check whether each product supports export order preparation, then use the table below to prepare a clearer RFQ.
| Criterion | What To Check | Why It Matters | Buyer Tip |
|---|---|---|---|
| Point Type & Drill Capacity | Confirm TEK point number matches base material thickness | Wrong point fails to penetrate steel gauge, causing stripped holes | Request drill-point capacity chart from Wuyang before finalizing RFQ |
| Thread Pitch & Spacing | Specify coarse or fine thread per substrate (metal vs. wood framing) | Mismatched pitch reduces pull-out strength in export assemblies | State substrate material clearly in your RFQ to get correct thread spec |
| Head Style & Drive Type | Match hex washer, pan, or bugle head to installation tool on buyer's line | Incompatible drive wastes labor and increases rejection rate at destination | Send a sample driver bit size with your inquiry to confirm fit |
| Coating & Corrosion Rating | Verify zinc plating hours (salt spray) meet destination climate requirements | Insufficient coating causes field corrosion complaints and warranty claims | Ask for salt-spray test reports when ordering for coastal or humid markets |
| Packaging & Bulk Order Format | Confirm box count, inner carton weight, and pallet configuration | Incorrect pack format raises freight cost and delays customs clearance | Include target port and Incoterm in RFQ so factory quotes correct packing |
When evaluating a China 1-1/4 Self Drilling Screws Manufacturer, Factory & Suppliers, compare specification scope, material and finish options, customization path, lead times, and how clearly the supplier communicates during the inquiry stage. A useful RFQ explains the application context, destination market, target quantity, and any approval or inspection steps required.
This page is organized around RFQ preparation and application matching, helping your purchasing team move from a general product search to a structured set of questions ready to send to a supplier.
Begin by documenting exactly how the 1-1/4 self drilling screws will be used in your project. Note the base material being fastened, the thickness of the substrate, the load or environmental conditions, and any appearance requirements such as finish or head style. These details allow a supplier to recommend the correct point style, thread pitch, and coating rather than sending a general catalog.
Once the application is defined, compare suppliers on the full specification range they carry: material grades, available finishes, packaging formats, and whether private labeling or custom marking is offered. For export order preparation, include any destination-market compliance notes, target unit pricing, and whether you need bilingual documentation or specific carton labeling.
Before requesting a formal quotation, prepare your quantity range, required delivery window, port of loading preference, and the internal approval steps your team follows. If after-sales support matters to your organization, ask specifically how the supplier handles replacement requests, inspection discrepancies, or packaging damage claims on export shipments.
When reviewing supplier replies, pay attention to whether they ask relevant follow-up questions about your application. A supplier that seeks clarification on installation conditions or end-use requirements is generally easier to work with on bulk orders than one that responds only with a price list. Use that communication quality as part of your shortlisting process.
| Criteria | Importance | Description | Example Options |
|---|---|---|---|
| Point Type | Application fit | Drill point number determines penetration capacity through specific substrate thickness | Point #2 for thin sheet; Point #3 for heavier steel |
| Thread Pitch | Holding strength | Coarse threads suit softer substrates; fine threads suit harder metal framing | 14-14 vs. 14-20 thread options |
| Surface Coating | Corrosion resistance | Coating choice affects suitability for indoor, outdoor, or marine export markets | Zinc vs. dacromet for humid climates |
| Head & Drive Style | Installation compatibility | Head type must match tool availability and load distribution needs at job site | Hex washer head for roofing; pan head for panels |
| Packaging Format | Bulk order logistics | Export carton configuration affects container utilization and customs declaration | Box of 1000 pcs vs. bulk 25 kg carton |

The top products highlighted here are frequently requested by factory purchasing teams organizing export orders for 1-1/4 self drilling screws. They cover the most common application scenarios and serve as a practical starting point for confirming specifications, requesting samples, or shortlisting items for your RFQ.
Self tapping screws are a practical fastening solution for thin metal sheets, brackets, ducts, housings, and many metal-to-metal assemblies. They form or cut mating threads as they are driven, reducing the need for separate tapping operations. To use self tapping screws in metal successfully, select the screw for the metal type and thickness, prepare a correctly sized pilot hole when required, keep the driver perpendicular to the surface, and stop...
How thick metal self-tapping screws can go through depends on the screw type, drill-point design, diameter, material hardness, installation method, and the manufacturer's tested drilling capacity. There is no single thickness limit that applies to every self-tapping screw. Standard self-tapping screws are commonly used with a pre-drilled pilot hole in metal. They form or cut mating threads as they are driven into the prepared hole. Self-drilling screws, often called TEK-style...
The short answer: it depends on the screw and the material. Some self-tapping screws can be driven straight in with no pilot hole at all; others will split the workpiece, strip their threads or snap the head without one. Getting this decision right is the difference between a fast, clean installation and a damaged part. This guide explains exactly when pre-drilling is required, when you can skip it, how to...
A self-tapping screw creates its own mating thread as it is driven into a material. Instead of requiring a pre-threaded hole, the screw cuts, forms, or displaces material to produce a secure fastening path. This makes it useful in metal, plastic, wood, composite panels, and many assembly applications where speed and efficiency matter. In manufacturing, construction, furniture production, appliance assembly, automotive parts, and electrical equipment, self tapping screws help reduce...
It's one of the most common questions in DIY and light fabrication - and the honest answer is: it depends. A self-tapping screw in thin sheet metal might hold 50-150 lbs, while the same-size screw driven into hardwood could hold several hundred pounds. There is no single number, because the holding power of a screw is decided by at least six variables working together. That doesn't mean you have to...
Self-tapping bolts are a go-to fastening solution for professionals and DIYers alike, thanks to their ability to cut their own threads as they are driven into a material. Whether you are working with sheet metal, plastic panels, or soft wood, understanding how to install a self-tapping bolt correctly is essential for achieving a secure, long-lasting joint without damaging the workpiece. Unlike conventional bolts that require a pre-threaded hole, self-tapping bolts...
