Key Considerations When Buying Speed Bump Fixings
Before choosing the best fixings for your speed bumps, consider the following factors to ensure they meet your functional needs:
Compatibility
What type of surface will you be fixing your speed bump to? The fixing should be compatible with the surface it will be installed on. For instance, tarmac-specific anchors or concrete bolts are designed to perform best on their respective surfaces. Sometimes, the design and material of a plug will determine the type of material your fixing can be used in.
Installation Method
Consider the ease of installation. Some fixings may require adhesives, fillers or specialised tools, while others only require a simple drill hole in the ground.
Use Case
For temporary speed bumps, be sure to pick a fixing type that is relatively easy to remove!
Quantity
How many fixings do your speed bumps require? Ensure you have selected at least the same number of fixings as are needed to install your speed bump—depending on the width of your road, this can often add up to more than expected!
Strength of Fixing
How deep is your road material? The fixing is only as strong as the road around it, so a thin road may not be strong enough to hold your speed bump, even if you have the strongest fixing bolts. For example, use a larger fixing (such as the well nut or universal fixing) to distribute the load evenly over a larger area in loose or crumbly tarmac.
Finish
Will your fixing see specific forms of wear and tear? Consider a fixing that resists this, such as rubber fixings for areas that see lots of vibrations (such as busy roads or delivery bays) or a galvanised finish for an extra long lifetime in spaces that see a lot of corrosion. If the road is gritted often, choose a salt corrosion-resistant material like stainless steel.
Washer
Will you need a washer? Some of our bolts have washers built into their heads, to distribute the load over the whole head, applying less pressure to the drill hole, while others do not. Consider whether a washer is necessary when choosing your bolts.
