This high-quality furniture connector screw is designed for secure and durable assembly of wooden panels, cabinets, and flat-pack furniture. Featuring a flat countersunk head with a hex socket drive, it allows for a flush, neat finish while ensuring a firm hold. The deep, sharp threads provide an excellent grip in wood, particleboard, and MDF, reducing the risk of loosening over time.

A fine-threaded self-drilling screw is a highly specialized fastener designed to quickly and efficiently penetrate thin metal sheets without the need for pre-drilling. These self tapping screws fine thread are equipped with a sharp, self-drilling tip that acts like a drill bit, allowing them to create their own pilot hole before the threading engages with the material to secure the fastener in place.
Fine-threaded Self-drilling Screw Features
Self-Drilling Capability: These fine thread self tapping screws come with a drill point that allows them to create their own hole as they are driven into the material. This eliminates the need for pre-drilling, saving time and simplifying the installation process.
Fine Thread Design: The fine threads are designed for precision and provide a tighter grip compared to coarse threads. This makes them ideal for use in thinner materials or for applications requiring a more secure fastening.
Enhanced Holding Power: The fine threads engage more surface area within the material, offering superior holding power and reducing the risk of stripping or loosening over time.
Smooth Finish: Fine thread self drilling screws often provide a smoother finish, which is beneficial in applications where appearance matters or where a flush fit is required.
As a fastener manufacturing factory, we will do our best to meet all the needs of customers.
ZLD Precision Mold manufactures drill point dies used in self-drilling and self-tapping screw production. The tooling covers L1-L7 series, IFI #4-#14 and DIN ST2.9-ST6.3, with HSS and tungsten carbide material options. Dies can be made from drawings, samples, screw specifications or production requirements. Applications include self-drilling screw forming, cold heading tooling and screw production lines. Final dimensions, price and lead time are confirmed against the buyer drawing, sample or production requirement.
Screws can be selected from ordinary, gradual, mutational, pinned, shielding, separating and exhausting types. The compression ratio of screw can be designed according to different raw materials and requirements of clients.
This company produces the SJZS series cone-shape double screw rodplastic extruding machine, has forces to squeeze out, high grade, thecompatibility broad, the life long, the shear rate small, the materialis not easy to decompose, to mix builds up the plasticizing to be good, the powder material directly takes shape and so on the characteristic, provides the direct current velocity modulation, the temperature automatic control, installment and so on vacuum exhaust. Is suitable to product the and so on tube, board, different shapematerial production.
The bimetallic barrel for single screw is a kind of barrel moulding 2-3mm thick alloy coat on the barrel inner wall which has excellent corrosion resistance, abrasion resistance and high working temperature. And its useful service life is greatly improved contrast to the common nitrided cylinder. Bimetal has more obvious advantages when processing special plastics to enhance the abrasion life, such as engineering plastic, fluorine plastics, PPO and etc.
The company product's single/twin screw, uses special alloy powders being sprayed and welded on the screw's ridge, and uses different alloys and welding methods for the screw of different functions.

PATTA self-drilling Chipboard screws have a coarse thread and fine shank to provide maximum grip and minimum strip out into chipboard, MDF board and soft timbers. The head has ribs molded around the countersunk head which help remove the chipboard particles when countersinking.
How to Use
1. Measure the total thickness of the materials to be fastened.
2. Choose a screw long enough to provide approx. 20mm of thread embedment into the chipboard or wood being fastened to.
3. Fit a #2 Phillips drive bit to a power screwdriver set to low speed, approx. 1000rpm.
Hex washer head
Sheet metal screw with a hex head and a washer attached.
* Zinc plated steel
* Steel is zinc plated for moderate protection against rust.
* Stainless steel 18-8
