Pambuka produk

Washers flat digunakake kanggo nambah lumahing prewangan saka kacang utawa sirah fastener supaya nyebar pasukan clamping liwat wilayah sing luwih gedhe. Padha bisa migunani nalika nggarap bahan alus lan bolongan gedhe utawa ora duwe aturan baku.

Ukuran mesin cuci nuduhake ukuran bolongan nominal lan adhedhasar ukuran sekrup. Dhiameter njaba (OD) mesthi luwih gedhe. Ukuran lan OD biasane ditemtokake ing inci pecahan, sanajan inci desimal bisa digunakake tinimbang. Ketebalan biasane kadhaptar ing inci desimal sanajan kita asring ngowahi dadi inci pecahan kanggo penak.

Grade 2 flat washers should only be used with Grade 2 hex cap screws (hex bolts)—use hardened flat washers with Grade 5 and 8 cap screws. Because Grade 2 flat washers are made of soft, low carbon steel, they will "yield" (compress, cup, bend, etc.) under the higher torque values normally associated with Grade 5 and 8 cap screws. As a result, there will be a reduction in clamping force as the washer yields.

Mesin cuci datar umume kasedhiya ing macem-macem bahan kalebu aluminium, kuningan, nilon, tembaga silikon, stainless steel lan baja. Baja sing ora dilapisi utawa ora dilapisi, diarani "rampung kosong," durung diolah kanggo nyegah karat kajaba lapisan lenga sing entheng kanggo perlindungan sementara. Akibate, finish umum kanggo baja yaiku seng plating lan hot dip galvanizing.

Aplikasi

Liwat desaine, properti distribusi mesin cuci kosong bisa nyegah karusakan apa wae ing permukaan sing dipasang. Mesin cuci datar nduweni permukaan sing tipis lan rata kanthi bolongan ing tengah. Mesin cuci jinis iki nyedhiyakake dhukungan kanggo sekrup sirah sing luwih cilik.

Black-oxide steel washers are mildly corrosion resistant in dry environments. Zinc-plated steel washers resist corrosion in wet environments. Black ultra-corrosion-resistant-coated steel washers resist chemicals and withstand 1,000 hours of salt spray.
