ISO4161 Geomet Finish Steel Grade 8 Serrated Flange LockNuts
ISO4161 Geomet Finish Steel Grade 8 Serrated Flange LockNuts Made
In China.
Serrated hex flange nut have enlarged circular base distributes
heavy pressures equally in order to assure a secure hold.
Large base requires a greater amount of torque to loosen and will
cover an oversized or poorly aligned hole.
We offer low carbon steel, medium carbon steel, alloy steel,
stainless steel and brass, aluminum alloy Washers.
Flange nuts can be heated, oxidized black, galvanized, hot bucket
galvanized, black zinc, copper plating, nickel plating, chromium
plating, Dakota and other treatments to meet various corrosion

| Application | Flange nuts have a washer-like base to distribute pressure over a
greater surface area and ensure the fastener stay tight. They are commonly used in manufacturing assembly lines where
operations are speeded by using a single fastener instead of a nut
and washer. |

Features:
Metric Medium-Strength Steel Flange Nuts—Class 8
No need for a washer—these metric medium-strength steel nuts have a
flange that distributes pressure across its surface the way a
washer does. Skipping the washer saves assembly time.
Sometimes called collar nuts, the flange gives these nuts a wider
profile than standard nuts, so they may not fit in tight spaces.
Made of medium-strength, Class 8 steel, they’re suitable for
fastening most machinery and equipment.
All meet DIN 6923 and some meet ISO 4161 dimensional standards,
which confirm their compatibility with other parts and tools. The
two standards are functionally equivalent.
Unfinished steel nuts are best for dry environments, since moisture will cause
them to rust. They are ready for painting and welding.
Zinc-plated steel nuts resist rust, extending their life
