How to Bolt a Bench Grinder Stand to a Concrete Floor

Secure a bench grinder stand to concrete using a few basic tools.

Most work benches and stands feature predrilled holes at the bottom of their legs. When securing a work bench to a concrete floor, use a hammer drill, masonry bit and wedge concrete anchors. Concrete anchors feature a sleeve with a threaded bolt inside. On top of the bolt is a nut that is threaded on. When the nut is tightened, the bolt inside the sleeve will lift and the sleeve will expand. The expanding sleeve will fill any voids inside the hole and will secure the bench into place.

Things You'll Need

• Work bench
• Pencil or marker
• Hammer drill
• Masonry bit
• Tape measure (optional)
• Tape (optional)
• Wedge concrete anchors
• Wrench or ratchet with sockets
• Safety glasses
• Dust mask
• Earplugs

Instructions

1. Place the bench grinder stand on the spot where you would like to secure it to the concrete floor. Pencil in each predrilled slot on the work bench legs to indicate where a bolt can be slipped through for securing purposes. Move the work bench to expose the marked floor.

2. Equip the hammer drill with a masonry bit that corresponds with the diameter of the anchor being used. Adjust the drill's depth gauge to the desired hole depth to accommodate the expanding concrete anchor.

3. Place the tip of the masonry bit on the mark made on the floor. Hold the hammer drill at a 90-degree angle and drill the hole to the correct depth. Repeat the process until the bench is secured to the concrete floor.

4. Slide the wedge anchors into the holes. Remove the nuts located at the top of the anchors. Set the work bench over the bolts so they sit inside the predrilled slots at the bottom of the bench legs.

5. Replace the nuts on the wedge concrete anchors. Thread the anchors by hand, turning them in a clockwise motion. Next, tighten the anchors with a wrench or ratchet and socket until they expand inside the concrete, which will secure the bench into place.

Tips & Warnings

• Wedge concrete anchors one-half inch in diameter are ideal for this task. Use a masonry bit featuring the same diameter as the anchor.

• Wear protective equipment, such as safety glasses, a dust mask and ear plugs, when operating power tools.

• Do not drill into concrete floors equipped with radiant heat unless you're sure there are no utilities in the area.
