Taw qhia rau cov khoom:

Brass Copper DIN7991/931/933 Bolts muaj xws li ob hom: DIN7991 (CSK tiaj tus - lub taub hau nrog sab hauv hex socket) rau flush - haum installation, thiab DIN931/933 (hex taub hau nrog ib nrab / tag nrho threading) rau load - bearing kev twb kev txuas. Crafted los ntawm tooj dag / tooj liab, lawv muaj ntuj corrosion kuj, zoo heev hluav taws xob conductivity, thiab ib tug txaus nyiam golden tiav. Lub DIN7991 countersunk taub hau kom ib tug snag - dawb nto; DIN931 muaj ib nrab xov (zoo tagnrho rau tuab workpieces), thaum DIN933 nta tag nrho cov xov (tsim los ntawm - qhov). Muaj nyob rau hauv qhov ntau thiab tsawg los ntawm M2 mus rau M24, lawv tau siv dav hauv cov rooj tog zaum (kho kom zoo nkauj fastening), cov khoom siv hluav taws xob (cov khoom siv hluav taws xob), cov khoom vaj khoom tsev (cov khoom siv kho kom zoo nkauj), thiab cov cuab yeej precision (tsawg - profile kho), ntsuas qhov zoo nkauj thiab ua haujlwm.

Cov lus qhia rau kev siv:

DIN7991: Txhim kho siv qhov sib txuam nrog hex ciaj ntswj, nruj kom txog thaum CSK lub taub hau yog dej ntws tawm nrog cov khoom ua haujlwm (tsis txhob hla - nruj kom tiv thaiv cov khoom sib tsoo).

DIN931/933: Siv ib qho kev sib txuas sab nraud, ua raws li cov lus qhia torque pom zoo (nco ntsoov tias tooj dag muaj zog qis dua hlau, yog li tsis txhob muaj zog ntau dhau).
Rau kev saib xyuas: Ntxuav cov bolts tsis tu ncua nrog daim ntaub qhuav. Brass ib txwm tsim patina dhau sijhawm; Yog tias xav tau polishing, siv tooj dag - cov tshuaj ntxuav tshwj xeeb. Tsis txhob cuam tshuam rau lub sij hawm ntev rau cov kua qaub los yog alkalis kom khaws cov khoom tiav.
