M1-M20 Slotted countersunk head screws / Ti Gr2 DIN 963 CSK Head Bolt
Countersunk head screw, also called countersunk head screw, also known as flat machine screw, is a kind of construction part. The head is a 90-degree cone, similar to common wood screws. The head has tool tightening grooves, such as a zigzag, cross, inner hexagon, plum blossom, pentagon, etc.
Screws are all connectors used to connect two objects. Generally, the head of the screw will protrude above the surface of the object to be connected, so that the surface will lose its smoothness. Countersunk head screws can sink under the surface to make the surface flat, and hard objects need to drill countersunk holes in the corresponding position of the countersunk head. In short, the countersunk head is the head of the screw that can keep the surface flat after installation.

Material:
Titanium alloy has high strength and low density, good mechanical properties, good toughness and corrosion resistance. In addition, the process performance of titanium alloy is poor, cutting is difficult, and it is very easy to absorb impurities such as hydrogen, oxygen, nitrogen and carbon during hot processing. There is also poor wear resistance and complex production process. The most widely used titanium alloys are Ti-6Al-4V (TC4), Ti-5Al-2.5Sn (TA7) and industrial pure titanium (TA1, TA2 and TA3).
Chemical composition: balance of titanium (Ti), nitrogen (N) ≤ 0.03, carbon (C) ≤ 0.08, hydrogen (H) ≤ 0.013, iron (Fe) ≤ 0.20, oxygen (O) ≤ 0.15
Mechanical properties: Tensile strength: 340Mpa≤σb≤410Mpa, yield strength σb≥165Mpa: Elongation: δ≥27%
