Q:What are the technical requirements for fasteners?
Name: Bolt nut flat cushion pad - (should be written in the national label) Drawing No .: Ask the engineer Material: Q235 Q235 steel spring steel ---- ordinary 35 steel 35 steel spring steel ---- high strength ratio: according to the actual Drawing quality: check the information or do not fill the level: 4.8 5 200HV 65MN ------ ordinary 8.8 8 300HV 65MN ------ high strength specifications: write their own
Q:what parts do Fasteners include
Bolts: A fastener consisting of a head and a screw (with an external thread), which is fitted with a nut for fastening the connection of two parts with through holes.

One of the most accurate A, C level of the most inaccurate, B between the two. Class A is used for important applications where assembly accuracy is high and subject to greater impact, vibration or variable loads. Class A for d = 1.6-24mm and l ≤ 10d or l ≤ 150mm bolts. B grade for d> 24mm or l> 10d or l ≥ 150mm bolts, thin rod B grade M3-M20 hexagonal flange bolts, anti-loose performance better. Class C is between M5 and M64.
