Tus kheej -tapping screws tuaj yeem ncaj qha txias-extrude cov xov sab hauv hauv qhov chaw tiaj, yog li ua tiav qhov cuam tshuam haum yam tsis tas yuav tsum tau ua ntej -tapping threads. Qhov no tshem tawm cov txheej txheem ua ntej -tapping, txo lub sijhawm fastening, txhim kho kev sib dhos ua haujlwm, thiab txo cov nqi tsim khoom. Tsis tas li ntawd, tus kheej -tapping locking screws muaj qhov yuav tsum tau tsav lub zog qis.
Tus kheej -tapping screws muab kev ua haujlwm zoo tshaj plaws ntawm kev kaw haujlwm thiab tiv thaiv- lub peev xwm xoob, nrog rau kev xauv lub zog nce los ntawm 50% mus rau 60%. Piv txwv li, cov nyhuv xauv tuaj yeem txhim kho ntxiv ntxiv-thiab xoob los ntawm kev vibration tiv thaiv- los ntawm kev sib txuas cov txheej txheem ntxhua khaub ncaws lossis los ntawm kev siv cov serrations nyob rau hauv qab ntawm lub taub hau ntsia hlau uas cuam tshuam nrog sab nraud - cov hniav xauv cov ntxhua khaub ncaws.
Tus kheej-tapping screws yog tus cwj pwm los ntawm qhov nyuaj ntawm qhov chaw ua ke nrog cov tub ntxhais zoo heev toughness-ib qho zoo uas feem ntau piav raws li "nyuaj rau sab nraud, tawv rau sab hauv." Qhov saum npoo hardness feem ntau tshaj 45 HRC, thaum lub hauv paus toughness yog khaws cia nyob rau hauv thaj tsam ntawm 28 mus rau 39 HRC. Rau siab -kev ua tau zoo ntawm tus kheej-tapping ntsia hlau, qhov nyuaj ntawm qhov chaw hauv qhov chaw tseem ceeb-xws li cov hlau lead- tuaj yeem ncav cuag tshaj 56 HRC, ua rau lawv txias-extrude threads ncaj qha rau hauv workpieces nrog lub hardness saum npoo tshaj 23 HRC.
