Sherex’s Full Metric Rivet Nut Line


Sherex Full Metric Rivet Nut Line

Purpose-Built for Metric Hole Sizes

Sherex’s full metric blind rivet nut line is engineered from the ground up for standard metric hole sizes — no oversized holes, no workarounds, just a direct fit into existing metric panel designs. The line was developed to meet the needs of European and North American manufacturers and assemblers using metric hole sizes. This product line will harmonize with ATLAS’ Full Metric Line.

Metric blind rivet nuts are popular in a wide range of industries, including:

Automotive
Heavy Truck
Data Centers
Enclosures
HVAC
General Industrial

Available Body Styles

Half Hex

CHLM (large flange) ·
CHKM (small flange) ·
CHKI (small flange)

Strong anti-rotation in a more compact profile.

Round Knurled

CKLM (large flange) ·
CKKM (small flange)

Ideal for softer materials like aluminum and composites.

Round Smooth

COLM (large flange) ·
COKI (small flange)

Light-duty applications with minimal panel damage.

Countersunk

CKCM (knurled) ·
COCM (smooth)Flush-mount installations in 90° countersunk holes.

Inch-hole variants with metric threads are also available (COKI — smooth, small flange; CHKI — half hex), for applications that pair metric threads with fractional/inch drilled holes. Closed end variants available with most full metric parts.

Materials, Threads & Finishes

  • Thread sizes: M3 to M12
  • Materials: Steel, and a variety of platings upon request
  • Standard finishes: zinc plated with clear trivalent chromate
  • End styles: Open and closed end options available across most of the range, with sealed-end options on select large-flange styles for added protection against fluid or dust ingress
Why it matters: Standard imperial-body rivet nuts installed into metric holes often require oversized or non-standard holes, adding cost and complicating panel design for manufacturers working to metric specifications. Sherex’s full metric line removes that mismatch entirely — every body size is matched to a true metric hole, so panels can be designed and punched to metric standards from the start.

Sherex Full Metric Rivet Nut Products

Full and Half Hex Body Rivet Nuts

Full hex body rivet nuts provide superior anti-rotation (spin-out) performance, making them ideal for applications where reliability in the face of vibration and torque is crucial.

Installed into a pre-formed hexagonal hole, full hex rivet nuts outperform round body and half hex alternatives thanks to their larger cross-sectional area, providing superior pull-out, push-out, and thread performance.

Round Body Rivet Nuts

Round body rivet nuts are the most versatile and widely used rivet nut design. They install into a simple round hole and work across virtually any material, thickness, or application — making them the go-to starting point for most blind fastening specifications.

Sherex offers large flange, small flange and countersunk full metric round body rivet nuts for use in all applications.
