Precision Machined Metal Parts M10 X 30 Fine Adjustment Screw Cup Head With Hex Socket
Cup head with hex socket adjustment screws machined part for automobile steering is made of alloy steel 1045 with property class 10.9 and zinc free chrome finish for corrosion resistance .
Adjustment screw machined part has a cup or cylinder head which is be used for operated by a wrench . and there is a lower socket under head that is used for clip purpose like E clip . and the end point is with a leading when screw is under assembly , the middle section length is threaded part for secure and lock object .
Machined adjustment screws are made according to specific request of application and referred to DIN and ISO standard . standard head and threaded shaft .
Material for adjustment screws machined part is alloy steel 1045 with anneal and tapered treatment for good performance
|Tensile strength σb (MPa)||650|
|Yield Strength σs (MPa)||420|
|Elongation δ5 (%)||20|
|Reduction of area ψ (%)||55|
The hardness of adjustment screw machined part is up to HRC 45 after anneal and tapered . this hardness is enough for automobile steering operation .
Surely , there are more other materials that can be used to adjustment screw machined parts
● Mild Steel
SCM435 and 40Cro
● Stainless steel
SUS430 ,SUS304 ,SUS316
● Alloy steel
TA1 ,TA2 , TA4 , T40 ,Ti1 , Ti2 ,Ti4
Above extra materials are chosen according to the strength requests of final assembly and operations requirements .
Adjustment screw machined parts are plated in zinc chrome free for corrosion resistant based on RoHS environment friendly requests
|Salt sprey time||48 hours|
There are more finish for choices that to be applied for other applications .
|Zinc||Various color can be choosed and perfect on anti-corrosion|
|Nickel||Making the surface more bright and hardened and the performance of screws will be improved|
|Tin||it is very perfect to be anti-rust , and widely used to components|
|Brass||It is usually used with Nickel for more good anti-corrrosion.|
|Paint||Its powder paint with colors to prevent surface from rust.|
|Chrome||Chrome finish can improve the surface hardness of parts , and keep plating color in long time and corrosion resistance .|
