The former can be screwed onto the end of mechanical components with external threads, while the latter can be screwed onto the end of mechanical components with internal threads. They are used to protect optical components, prevent dust, and block light. The knurled edges on the end caps facilitate tightening and removal.\u003C/p>",{"productTabNameId":287,"tabName":291},"Assembly",["Reactive",293],{"$snuxt-i18n-meta":294},{},["Set"],["ShallowReactive",297],{"$fvpUpa8LH8tCwp-18lSLZ5DkPh0mhQrRmdb45RQuidoo":-1,"$fKUUIOjAeSHVCatg9x5tBVcMjPfqAmR42SkHRWrV1m4k":-1,"$fY1uzuOuOMCIrsnfZ136F21V9dQQAaB0QqtOQVyyGGVI":-1},"/product/143?fid=36&tid=97",{"myAppGlobalStore":300,"myAppCartStore":313,"MetayImgPreviewStore":319,"myServiceModalStore":325,"myAppCompareStore":327},{"sessionId":301,"token":302,"surveyLink":304,"navCategory":305,"topAds":308,"feedbackType":310},["Ref",75],["EmptyRef",303],"_",["Ref",74],["Ref",306],["Reactive",307],[14,19,24,29,34,39,44,49,54,59,64],["Ref",309],["Reactive",12],["Ref",311],["Reactive",312],[],{"cartNum":314,"cartData":316},["EmptyRef",315],"0",["Ref",317],["Reactive",318],{},{"visible":320,"previreList":322},["EmptyRef",321],"false",["Ref",323],["Reactive",324],[],{"visible":326},["EmptyRef",321],{"compareIds":328,"compareList":331,"compareVisible":334},["Ref",329],["Reactive",330],[],["Ref",332],["Reactive",333],[],["EmptyRef",321]]
