About Structural Dome Rivets
Structural Dome Rivets (Anlock / Mega Lock) are high-strength blind rivets with a mechanical lock that retains the mandrel inside the body after install. The retained mandrel doubles or triples the shear and tensile strength compared with a standard pop rivet of the same diameter. Used in trailer manufacture, truck and bus body assembly, light structural steel, mining and heavy-equipment panel work, and any vibrating joint where a standard rivet would loosen or shear.
Recommended use Marine, coastal, food-grade, chemical-exposure and any outdoor application where corrosion resistance must extend across the entire rivet body.
Measure the body diameter and the shell length end to end. Our step-by-step guide shows exactly where to measure, with diagrams for every head type.
Add up the layers you are joining, then pick a rivet whose Grips range covers the total. Every product name shows its grip range.
Frequently Asked Questions
Brand names include Anlock, Mega Lock, Magna Lok, Avdel Avseal, Huck Magna-Bulb. All work on the same principle: the rivet sets like a normal pop rivet but a locking ring captures the mandrel as it breaks, leaving it permanently inside the body. Used in trailer manufacture, transport (truck and bus bodies), light structural steel, and any vibrating assembly where a standard rivet would loosen or lose strength when the mandrel falls out.
Standard pop rivets rely entirely on the body material for clamp and shear; their mandrel breaks off and falls out, leaving a hollow body. Structural rivets keep the mandrel locked in, which doubles or triples the rivet's effective shear area and prevents the body collapsing under load. Worth the extra cost on any joint that sees vibration, impact or dynamic load.
Structural rivets have noticeably wider grip ranges than the equivalent standard rivet, so one product often covers several panel-thickness scenarios. Always confirm the grip range includes your actual stack-up.
Drill approximately 0.1 to 0.2mm larger than the body diameter. Hole size tolerance on structural rivets is tighter than on standard rivets; an oversize hole reduces the rivet's load rating.
Setting a 6.4mm structural rivet by hand is hard work; consider a battery rivet gun for any volume install. Confirm the tool's nose-piece matches the rivet diameter before starting.
Anywhere the joint sees real shear load, vibration, or impact. The locked-in mandrel is the difference: a standard pop rivet under cyclic load eventually loses its mandrel and slackens; a structural rivet stays tight.
Material & Coating
Shell (body) and Stem (mandrel) Both the shell (the visible cylindrical body that expands to clamp the joint) and the stem (the inner mandrel pulled by the rivet tool) are stainless steel. No galvanic mismatch between the two parts, and no internal rust path after the stem breaks off.
Important Higher install force than aluminium / steel. Use a rivet tool rated for stainless. Stainless on stainless can gall under high install torque; squeeze slowly and steadily.
How to Measure
Rivet Length This rivet has a head that sits proud of the work face, so the length is the shell length - measured from directly under the head to the bottom of the shell body, excluding the mandrel bubble at the end. The head itself is not included in the size.
