Self-Drilling Tek Screws

Zopangira zodzibowolera zokha, kapena Tek zomangira, onani kugwiritsidwa ntchito pafupipafupi pakuwotcha kwamalonda ndi kukhazikitsa zoziziritsa. Zomangamangazi zimakhala ndi maupangiri obowola, omwe amalola ogwiritsa ntchito kudumpha ntchito yobowola kale ndi zotetezedwa mwachisawawa, makamaka ma sheet. Zomangira za Tek ndizofunika pamapulogalamu angapo, ndi mapulojekiti ofolera zitsulo kukhala amodzi omwe amapezeka kwambiri.

Tili ndi zosankha zambiri za misomali, zomangira, ndi zomangira zina zamitundu yonse ya ntchito zomanga. Timapereka Tek yodziboolera^® zomangira mu carbon steel komanso mitundu iwiri ya zitsulo zosapanga dzimbiri, 410 ndi 18-8, ndi mwayi wokhala ndi mitu yopenta kuti igwirizane ndi malo osiyanasiyana, ndi makulidwe osiyanasiyana a shank alipo kuti amalize ntchito iliyonse yachitsulo pazitsulo yomwe mukugwira. Tiyeni tikuthandizeni kuti ntchitoyi ichitike bwino ndi zida zathu zopulumutsa nthawi.

Makulidwe Osiyanasiyana a Tek Screws

Pulojekiti iliyonse imafunikira zomangira zapadera kuti ikwaniritse cholinga chomwe wapatsidwa. Pa screw, shank ndi gawo lalitali, la ulusi lomwe limalumikiza nsonga ndi mutu. Nthawi zambiri mumafunika shank kuti ikhale yokulirapo kuti igwirizane ndi chitsulo chomwe mukugwira nacho. Ganizirani za ndodo za ulusi ngati zovala - kukula kwa shank, kukula kwake. Momwemo, screw 10 idzakhala yayikulu kuposa nambala 8.

Mtundu wamutu wamutu womwe umafunikira ukhozanso kusiyanasiyana kutengera ntchito. Mtundu wodziwika kwambiri wamutu uli ndi mbali zisanu ndi imodzi zosalala ndipo umadziwika kuti hex head screw. Zomangira izi zimagwiritsidwa ntchito kwambiri m'makampani a HVAC, makamaka mutu wa 10 × 3/4 hex washer. Kuyeza pamutu wa zomangira zodzibowolera izi kukuthandizani kudziwa nambala ya shank. Miyezo itatu yodziwika bwino yamutu ndi zingwe zofananira ndi izi:

• 1/4 hex pagalimoto:Kukula 6 kapena 8 shanks.
• 5/16 hex pagalimoto:Shank size 10 ndi 12.
• 3/8 hex pagalimoto:Kukula 14 screw shank.

Zowononga zomwe zimagwiritsidwa ntchito ndi makampani otenthetsera ndi mpweya ndi 5/16, monga shank ya 10 imagwira ntchito bwino pomanga mapepala achitsulo.

Kumvetsetsa Mitundu Yanji ya Zopangira Zomwe Mukufunikira

Ngati ndinu kontrakitala, m'pofunika kuti mukhale achindunji momwe mungathere pofunsa mtundu uliwonse wa fastener. Tek^® zomangira zilidi zomangira zodziboola - zomangira zomwe zimadula ulusi wawo - koma sichifukwa cha nsonga yawo. Nsonga ndi kudzibowolera pomwe ulusi umadzigunda. Akamafunsa zomangira za tek, anthu ambiri amapempha chodzipukutira chomwe chitha kukupatsirani zomangira zolakwika popeza zomangira zachitsulo ndi zomangira zip komanso kudzigunda. Onetsetsani kuti mwafotokoza nsonga ya mfundoyo, ndipo muyenera kukhala wabwino. Timakonda kufotokoza ngati nsonga yamtundu wa kubowola kapena yofanana ndi fosholo. Pali kusiyana kumodzi kwakukulu pakati pa zomangira zamitundu iyi:

• Zomangira zokha:Ulusiwo umalola wononga kuti igwire ulusi wake muzinthu.
• Zomangira zosadzigunda:Zomangira zamakina ndi mtundu umodzi wa zomangira zamtunduwu. Amafuna mtedza wopangidwa kale kapena choyika china chachikazi.

Kudziwa kusiyana pakati pa mitundu yosiyanasiyana ya zomangira kumakupulumutsirani nthawi ndikukulolani kuti mubwerere kumalo ogwirira ntchito ndi zida zofunika m'manja.
