Provides high-strength threads in thin materials starting at 0.5mm.
Increased thread strength.
Safeguard design avoids overtightening problems such as thread stripping.
Assembly applications include tubular steel, hydroformed parts, magnesium castings, and aluminum extrusions.
Specifications:
Sizes: M6, M8, M10 and M12
Headforms: Large flange
Shape: Hexagon
Material: Steel Zinc plated to BS 3382 and clear passivated to achieve 240 hours resistance to red corrosion (ASTM B117) Hexavalent Chromium-free
For assistance with hexagonal hole production, see our 74290 tool. The 74290 tool allows customers to benefit from the non-rotational properties of hexagonal inserts compared with round inserts. This is achieved by drilling a round hole, then inserting the 74290 tool and forming a hex hole.
One fastener can be used to replace several standard grip fasteners.
Reduced fastener inventory and simpler stock control.
Compensates for irregular, oversized, slotted, or misaligned holes.
Can stop sheet movement in non-standard holes.
Large gap closing capability.
Provides very strong, vibration-resistant joints.
No damage, electrical problems, or rattling due to loose stems.
Breakstem fasteners can be customized to meet unique assembly requirements.

*Why 316 Grade / A4 Stainless Steel? The Monobolt® range has now been extended through the addition of a 316 Grade / A4 stainless steel Monobolt® suitable for applications in marine and hostile environments where 304Cu Grade / A2 stainless steel Monobolt® may not be the most suitable solution.
316 Grade has a higher nickel content than other alloys and contains molybdenum. The molybdenum allows the material to deliver enhanced corrosion resistance particularly to pitting and crevice corrosion. Additionally this alloy lends itself to both forming and welding without excessive cracking. For this reason, it is particularly good for assemblies in marine and hostile environments.
Multi-grip capability accommodates wide variations in material thickness.
One rivet can be used to replace several standard grip fasteners.
External splines fill rear sheet and oversize front sheet holes.
3x greater hole-size tolerance than standard breakstem rivets.
Far less sensitive to application variations.
Easier specification due to one-rivet x one-mandrel solution.
Typically half the installed weight versus an equivalent breakstem rivet.
Either magazine-fed or fed via a vibrating bowl to a wide choice of installation equipment.
Assembly applications where you will find NeoSpeed® fasteners include automotive, electronic, domestic appliance, electrical equipment, and general light fabrication.
Improves torque-to-turn by up to 350% in sheet metal compared to round-body inserts.
Increases punch life compared to hexagonal geometries.
Blind hole, one-sided installation capability.
Superior pull-out performance.
Can be used for very thin sheet materials from 0.50mm (0.02″).
Provide a female thread-in application.
Can be installed in pre-coated or post-painted applications without damaging the surface.
Clamp two or more sheets.
Various platings available to increase corrosion resistance.
Large-flange head provides a load-bearing surface and reinforces the hole to prevent push-out.
Can be used as a spacer and can be supplied with an underhead seal.
Assembly applications where the Squaresert® is used include automotive body mountings, electrical enclosures, soft sheet metal, plastics & composites, domestic appliances, and general light fabrication.
