Qhov ntau thiab tsawg ntawm Tek Screws

Txhua qhov project xav tau cov fasteners tshwj xeeb kom ua tiav lub hom phiaj muab. Ntawm cov ntsia hlau, lub shank yog qhov ntev, threaded ib feem uas txuas lub taub thiab lub taub hau. Koj feem ntau xav tau lub shank los ua qhov loj me kom haum rau cov hlau koj ua haujlwm nrog. Xav txog cov threaded rods zoo li cov khaub ncaws - qhov loj ntawm lub shank, qhov loj qhov loj. Xws li, tus lej 10 ntsia hlau yuav loj dua tus lej 8.

Hom lub taub hau style koj xav tau kuj txawv raws li txoj haujlwm. Lub taub hau nrov tshaj plaws nta rau sab tiaj thiab paub tias yog lub taub hau hex taub hau. Cov fasteners no feem ntau siv hauv HVAC kev lag luam, tshwj xeeb tshaj yog 10 × 3/4 hex washer taub hau. Kev ntsuas thoob plaws lub taub hau ntawm tus kheej-drilling screws yuav pab koj txiav txim siab tus naj npawb shank. Peb lub taub hau loj tshaj plaws thiab lawv cov shanks sib xws yog:

• 1/4 hex tsav:Loj 6 los yog 8 shanks.
• 5/16 hex tsav:Shank qhov ntau thiab tsawg 10 thiab 12.
• 3/8 hex tsav:Loj 14 ntsia hlau shank.

Cov ntsia hlau feem ntau siv los ntawm cov tuam txhab cua sov thiab huab cua yog 5/16, raws li qhov loj 10 shank ua haujlwm zoo rau kev txuas cov ntawv hlau.

Nkag siab yam ntawm Screws koj xav tau

Yog tias koj yog tus neeg cog lus, nws yuav tsum tau ua kom meej meej li sai tau thaum thov rau txhua hom fastener. Tek^® cov ntsia hlau yog qhov tseeb ntawm tus kheej tapping screws - screws uas txiav lawv tus kheej threads - tab sis nws tsis yog vim lawv lub ntsis. Lub ntsis yog tus kheej-drilling thaum threads yog tus kheej-tapping. Thaum nug rau tek ntsia hlau, ntau tus neeg nug txog tus kheej tapper uas tuaj yeem ua rau koj tsis raug ntsia hlau txij li cov ntawv hlau screws thiab zip screws kuj yog tus kheej tapping. Tsuas yog xyuas kom koj piav qhia lub ntsiab lus ntawm lub ntsiab lus, thiab koj yuav tsum zoo. Peb nyiam piav qhia nws li ib qho kev xyaum me ntsis los yog ib qho uas zoo li lub duav. Nws yog ib qho tseem ceeb sib txawv ntawm cov hom ntawm screws:

• Self-tapping screws:Cov xov tso cai rau cov ntsia hlau coj mus rhaub nws cov xov rau hauv cov khoom.
• Tsis-tus kheej tapping screws:Tshuab screws yog ib hom ntawm cov ntsia hlau no. Lawv yuav tsum tau ib tug pre-threaded txiv ntseej los yog lwm yam poj niam inserts.

Paub qhov txawv ntawm ntau hom fasteners txuag koj lub sijhawm thiab cia koj rov qab mus rau qhov chaw ua haujlwm nrog cov cuab yeej tsim nyog hauv tes.
