Hex Flange Nuts

Hex Flange Nuts for Automotive Structural Joints — Serrated and Flat Flange

Hex Flange Nuts

Hex nuts with integrated flange — the flange replaces a separate washer, distributes clamp load, and anti-rotation serrations (where specified) prevent backing-off under vibration. Paired with hex flange bolts, cold-forged structural bolts, and stud assemblies across automotive Tier 1 / Tier 2 programmes.

Supply across DIN 6923 (serrated), flat-flange variants, JIS B1190, and ISO 4161 specifications. Configurations matched per customer property class (class 6 / 8 / 10), thread pitch (coarse / fine), coating, and flange geometry per programme. Most competitive on programmes requiring PPAP / IMDS / CQI documentation alongside volume pricing — pure commodity-price programmes may find more competitive supply elsewhere.

05 · Flange geometry and property class

Flange profile (serrated for anti-vibration, flat for bearing distribution with separate washer), property class (6 / 8 / 10 for pairing with class 6.8 / 8.8 / 10.9 bolts), and coating (zinc flake, Dacromet, Geomet, phosphate) matched per customer torque spec and service environment — drawing-reviewed against bolt pairing and joint requirement.

Family coverage · 3 types

Selecting across hex flange nut types

Serrated Flange (DIN 6923)

Anti-vibration · mainstream

Serrated flange bearing face provides anti-rotation grip. Standard for automotive chassis, suspension, engine, and exhaust joints where continuous vibration requires locking nut function without an additional lock washer. Widely specified across DIN 6923 mainline automotive programmes.

Flat Flange

Bearing distribution · separate washer

Smooth flange bearing face. Used where a separate lock washer, chemical thread-lock, or nylon-insert is preferred over serrated engagement, or where the mating surface must not be marked by serrations.

High-strength · Class 10

Critical joints · paired with class 12.9 bolts

Property class 10 hex flange nut — heat-treated alloy steel for critical-joint applications paired with class 12.9 bolts. Cylinder head, main bearing caps, connecting rods, and other high-stress structural joints.

Body style (open / closed / hex / square / knurled), material grade, grip range (panel thickness tolerance), and head profile matched per substrate and installation method — drawing-reviewed against customer panel thickness, hole size, and installation tooling (hand, pneumatic, or automated rivet-nut tool). Established production capacity and active partner qualification supports rapid quotation and reliable delivery for volume programmes.

Selecting across blind rivet nut body styles

Open End

Standard · most common

Through-hole thread, open at the blind side. Standard rivet nut geometry — core production volume at Way Fast, supplied across most automotive and industrial applications where the installed fastener will not be exposed to moisture or debris.

Closed End

Sealed · moisture / debris protection

Sealed blind-side end — prevents moisture, debris, or foreign material from entering the fastener cavity. Used in exterior body panels, wet-environment enclosures, and clean-room assemblies.

Hex Body

Anti-rotation · hex hole

External hex-body profile. Installs into a hex-shaped hole in the panel — mechanical interlock with the hole prevents rotation during installation and service. Used where knurled grip alone is insufficient under high torque.

Square Body

Anti-rotation · square hole

Square-body variant of hex design — installs into a square hole for the same anti-rotation benefit as hex body. Selected where square hole production is preferred (stamping) over hex punching.

Knurled (Roulette)

Anti-rotation · round hole

External knurl on the body shank. Installs into a standard round hole; during installation the knurl grips the hole wall preventing rotation. Most common anti-rotation variant when hex / square holes are not available.
