Partial thread screw is one of the non-standard screws, the general tail thread and no thread near the head. When the screw enters the preset hole, the chip scraped out by the tail thread can be discharged better, and less effort. Moreover, the rod diameter strength of partial thread screw is greater than the whole thread screw, and the yield strength is also higher. If there are requirements on the strength of the screw, it is recommended to choose partial thread screw. When producing long screw, full screw is more expensive than partial thread screw, this price difference still can increase with screw length and more obvious.

In general, the commonly used Inner Hexagon Screws are Grade 4.8, 8.8, 10.9, 12.9 and so on. OSWELL can choose from a variety of Inner Hexagon Screws grades based on customer requirements for better bolt performance. It can withstand greater loads because it has six stress surfaces and can withstand greater torque than a head screw or a cross screw. The rotation Angle of 60° can make the product installed smoothly in narrow space.

Set screw is a kind of screw specially used for fixing the relative position of machine parts. When in use, screw the set screw into the screw hole of the part to be fixed, and press the end of the screw on the surface of another part, even if the former machine is fixed on the latter one. Slotted and inner hexagon set screws are used on parts where the head is not allowed to be exposed, and square head set screws are used on parts where the head is allowed to be exposed . The slotted head type is not easy to damage, if damaged, it still can be used normally in the case of not serious.

Screws are indispensable industrial necessities in daily life. Small to glasses, clocks, electronics and so on, large to television, electrical products, musical instruments, furniture and so on Screws are ubiquitous and have important roles in industry. The slotted head type is not easy to damage, if damaged, it still can be used normally in the case of not serious. Stainless steel screws have good resistance to corrosion fatigue and wear corrosion. In some corrosive medium conditions are used in pumps, valves and other equipment.
