Low Profile Screws・Small Head Screws product listings. Ideal for making devices and equipment smaller and safer. NBK Official Website (Specialist Special Screw Manufacturer). M3 ～ M4: M3 ～ M4. 18-8 stainless steel screws have good chemical resistance and may be mildly magnetic. All are passivated for added protection against oxidation and corrosion. A Torx drive has more points of contact than other drives, allowing you to tighten the screw without damaging the recess. For Torx tools, see Torx and Torx-Plus bits, keys, and drivers. Length is measured from under the head. Choose from our selection of M4 screws in a wide range of styles and sizes. Torx: Torx Plus. With a deeper drive than flat and rounded head screws, socket.

Stainless Passivation Process Introduction
The stainless steel passivation liquid adopts the latest catalytic technology, so the passivation speed of the improved product is faster and the corrosion resistance is stronger than before. Through the passivation of this product, a dense passivation film can be formed at 5-15min, while maintaining the original gloss of the work piece without damage to the work piece size, and the performance of the neutral salt fog can be increased by 10-30 times.
Features
1.Operate under normal temperature, short passivation time: save energy effectively and improve efficacy;
2.No contain heavy metals: environment friendly;
3.Good stability: normal service life can reach more than one year;
4.Good salt fog performance: above 1500H.
Consumption Estimate
For cleaning of general stainless steel welding line and argon arc welding line, it needs about 0.5kg every one hundred meters;
M4 Torx Head Screws Fasteners
For cleaning of arc welding line, it needs about 1kg every one hundred meters;
For cleanup thick oxide on heat press end socket or heat treatment part, it needs about 1kg every two sq.m...
Technological Process
Degreasing --- Rinsing water --- Pickling --- Rinsing water --- Passivation --- Rinsing with running water--- Neutralizing --- Rinsing --- Cleaning with pure water --- Drying
Instructions
1.For cleaning of welding line oxide, first clean welding residue welding line and oily soil, then paint grease on the pretreated surface with the coating thickness is 1~2mm and resort about 1~2hours is needed, at last clean residues on the cleaning surface with cotton waste or rug (water washing is better) until bright and clean.
2.Excellent ventilation on the site during operation, the operator should wear rubber gloves & shoes and respirator. If closed environment during operation is existed, it must use ventilation system with two operators work together.
FLANGE BUTTON SOCKET SCREWS
Description:
Flange button socket screws from ITA Fasteners are protective fasteners which provide the assembly with structural support as well as a visually appealing look. It protects the components around it from damages like scraps and unintentional cuts. Another advantage of these screws is the large under head bearing surface - this eliminates the need for washers. It could also be considered as a built-in washer. These screws are fully threaded to provide its users with grip and accurate positioning.
Although these screws have a considerably high load bearing strength, it is not advisable to use them in high strength applications. The stainless steel, carbon steel or alloy steel make gives these screws an additional corrosion resistant property. They are mostly used in applications where the surface area of operation is not sufficient enough for the usage of a wrench. This means that they are often used in machining and assembly processes which do not exert too much torque on its body.
