Reduces excess space requirements within the chassis.
Common hole form can be used throughout the chassis design to reduce complexity.
Can be installed from either direction if accessible.
Expands radially in the material during installation.
Provides superior joint strength when compared to competitive technologies.
One-piece fastener eliminates potential stem fall out that can cause electrical problems.
Rapid installation with magazine or bowl feed fasteners.
Available as a customized design to meet your unique assembly requirements.
Popular electronics industry assembly applications include computer chassis, casings, small electronic devices, and applications with exceptionally thin sheet.
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.
