Khoom Taw Qhia

Hex txiv ntseej yog ib qho ntawm cov txiv ntseej uas muaj ntau tshaj plaws thiab siv nrog cov thauj tog rau nkoj, bolts, screws, studs, threaded rods thiab lwm yam fastener uas muaj tshuab ntsia hlau threads.Hex yog luv rau hexagon, uas txhais tau hais tias lawv muaj rau sab.Hex n uts yog yuav luag ib txwm siv nrog ib tug mating bolt kom fasten ntau qhov chaw ua ke.Ob tus neeg koom tes yog khaws cia ua ke los ntawm ib tug ua ke ntawm lawv threads 'kev sib txhuam (nrog me ntsis elastic deformation), me ntsis stretching ntawm lub ntsia liaj qhov rooj, thiab compression ntawm qhov chaw. los tuav ua ke.

Txhawm rau kom paub meej tag nrho cov xov sib txuas nrog cov txiv ntoo hex, bolts / screws yuav tsum ntev txaus kom tso cai tsawg kawg yog ob lub xov tag nrho kom ntev tshaj li lub ntsej muag ntawm lub ntsej muag tom qab zawm.Thiab, yuav tsum muaj ob lub xov tag nrho nthuav tawm ntawm lub taub hau ntawm cov txiv ntoo rau xyuas kom cov txiv ntseej tuaj yeem nruj kom zoo.

Daim ntawv thov

Hex txiv ntseej tuaj yeem siv tau rau ntau yam kev siv uas suav nrog kev tuav cov ntoo, hlau, thiab lwm yam khoom siv rau cov haujlwm xws li cov chaw nres nkoj, txuas hniav, cov qauv kev loj, thiab cov tsev.

Black-oxide steel screws are mildly corrosion resistant in dry environments.Zinc-plated steel screws resist corrosion in wet environments.Black ultra-corrosion-resistant-coated steel screws resist chemicals and withstand 1,000 hours of salt spray .Coarse threads are the industry standard; choose these Hex nuts if you don’t know the threads per inch.Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.

The Hex nuts is designed to fit a ratchet or spanner torque wrenches allowing you to tighten the nuts to your exact specifications.Grade 2 bolts tend to be used in construction for joining wood components.Grade 4.8 bolt s are used in small engines.Grade 8.8 10.9 or 12.9 bolt s provide high tensile strength.One advantage nuts fasteners have over welds or rivets is that they allow for easy disassembly for repairs and maintenance.
