Flat Washer, Zinc-Plated, Hardened HV
Hardened HV zinc-plated flat washer per DIN 9021, DIN 125 and GOST 11371-81, M5–M36, diameter 10–66 mm. FLOK supplies it for high-load threaded joints.
Flat washer, zinc-plated, hardened HV, is made of high-strength steel followed by electrolytic zinc plating. In technical parameters it complies with the German standards DIN 9021 and DIN 125, and the Russian GOST 11371-81. HV flat washers are designed to form threaded fastening joints in structures under high loads. They have the shape of a closed flat ring. They are installed under the nut or under the head of a bolt, screw or stud.
Flat washers, zinc-plated, hardened HV, are an in-demand type of fastener. When choosing, it is important to consider not only the physical characteristics but also the dimensions. The range includes a central hole diameter for metric thread M5–M36, an outer size from 10 mm to 66 mm, and a thickness of 1–5 mm.
The use of these fasteners creates strong joints without damaging the base surface. The washer evenly distributes the joint load and prevents the fastener from loosening spontaneously.
