Mounting Dowels and Screws

Anchors and Screws for Delineators, Speed Bumps and Road Studs

Our mounting screws and asphalt anchors fix delineator posts, speed bumps and road studs firmly to asphalt or concrete. Alongside surface-mount hardware, this category also covers the bolts and clamps used to attach signs and secure pipes.

Product Range

• Mounting screws: separate models for asphalt and concrete, used to fix delineator and speed bump bases.
• Plastic asphalt and concrete anchors: give the screw a secure grip in the surface.
• Road stud nails: for fixing road studs to the pavement.
• Traffic sign bolts and nuts: for attaching signs to clamps and posts, also in packs of 20.
• Galvanized U-bolt clamp: for securing 3-inch pipes.

Pack Sizes

Screws and anchors are available individually and in packs of 10, 100 and 1000. Packs of 10 suit small repairs, packs of 100 suit car parks and site work, and packs of 1000 suit road projects and resellers.

Installation Tips

• Match the anchor to the surface: asphalt anchors on asphalt, concrete anchors on concrete.
• Mark the holes through the mounting holes in the product base.
• Clean out the dust after drilling, insert the anchor and drive the screw.
• Do not overtighten; plastic bases can be damaged.

Frequently Asked Questions

What is the difference between asphalt and concrete anchors? The two surfaces differ in hardness and structure. Each anchor is designed for its own surface, which helps keep the screw from loosening over time.

How many screws does a delineator or speed bump need? One screw and anchor per mounting hole in the base; check the hole count on the product page before ordering.

Which pipes does the U-bolt fit? It is made for 3-inch pipe; we recommend measuring your pipe's outer diameter before ordering.
