Mounting Hole Diameter for MOLLE Panels: How to Choose Yours

How do I measure my required Mounting Hole Diameter?

To establish your required Mounting Hole Diameter, you must identify the exact fastener you plan to use before ordering a Molle Storage Panel.

The most reliable method is to measure the outer diameter of the threaded shank of your bolt. Use a digital caliper to get an accurate reading in mm, as even a 1 mm difference can prevent a bolt from passing through a pre-drilled hole.

If you do not have the hardware on hand, look for the thread pitch and size on the packaging or the manufacturer’s documentation. For example, a standard M8 bolt is designed for an 8 mm diameter shank.

Once you have the shank diameter, add a small clearance margin. For most standard applications, adding 0.5 mm to 1 mm of clearance to the bolt’s diameter provides a smooth fit that accounts for manufacturing tolerances in the Molle Storage Panel.

Verify your measurements against the vehicle’s mounting points. If the vehicle’s existing holes are smaller than the bolt you intend to use, you may need to confirm that the mounting surface can be modified by a qualified installer before selecting a panel.

Beginners can learn the basics by reading how a molle panel works and functions.

What happens if the Mounting Hole Diameter is wrong?

A Mounting Hole Diameter that is too small results in a failure to install the hardware. If the hole is even slightly smaller than the bolt shank, you will be unable to pass the fastener through the Molle Storage Panel without damaging the material.

Attempting to force a bolt through a hole that is too small can lead to shear stress failure. This occurs when the pressure causes the mounting hole to elongate into an oval shape or causes the panel to tear at the point of contact.

A Mounting Hole Diameter that is too large creates a different set of issues regarding stability and vibration fatigue. If the hole is significantly larger than the bolt, the hardware will have too much “play” within the panel.

This movement allows the Molle Storage Panel to rattle against the mounting surface. Over time, this constant vibration can lead to mounting point misalignment, where the panel shifts out of its intended position, or it can cause the fasteners to loosen and eventually fail under the weight of the gear.

What do I do if my hardware falls between two sizes?

When your specific hardware falls between two standard Mounting Hole Diameter options, you should prioritize a slightly larger hole over a smaller one.

A hole that is slightly too large can be compensated for by using a larger washer or a backing plate to distribute the load and eliminate movement. A washer provides a wider surface area, ensuring the hardware remains seated firmly against the Molle Storage Panel.

Conversely, a hole that is too small cannot be corrected without drilling out the material. Drilling into a Molle Storage Panel after purchase can compromise the structural integrity of the panel, especially if the material is thin-gauge aluminum or steel.

If you are unsure of the exact clearance needed, consult the manufacturer of your mounting hardware to confirm the maximum shank diameter. Ensure that the final Mounting Hole Diameter you select allows for the bolt, a washer, and any necessary clearance for a nut or thread engagement.

Always confirm your final measurements with a qualified installer before finalizing your order. A professional can ensure that the chosen diameter provides the necessary clearance for the specific mounting environment of your vehicle.
