About Threaded Studs and Rods

Steel Wood Screw Threaded Studs
These studs are also known as hanger bolts—use them to hang, mount, and fasten parts to wood structures. Install with a stud driver or create wrench flats by threading two nuts onto the stud and jamming them together.
Black-oxide steel studs are mildly corrosion resistant in dry environments.
Zinc-plated steel studs resist corrosion in wet environments.

Vibration-Resistant Female-Threaded Anchors for Block and Brick
Often referred to as four-way expansion anchors, these expand in four directions to resist loosening from vibration. To install, tap into a drilled hole with a hammer and position your fixture. Then, insert a screw or threaded rod and tighten. Pull-out strength and shear strength values are 25% of the ultimate values.

Female-Threaded Anchors for Block and Brick
Also known as double expansion anchors, these expand from both sides for full contact and a secure hold. To install, tap into a drilled hole with a hammer and position your fixture. Then, insert a screw or threaded rod and tighten. For maximum expansion, the anchor should protrude slightly above the surface before threading the screw. Pull-out strength and shear strength values are 25% of the ultimate values.

Female-Threaded Expansion Anchors for Hollow Block and Brick
For narrow holes and small cavities where toggle anchors won't fit. To install, tap the anchor cone first into a drilled hole. Then, insert a screw or threaded rod and tighten. Pull-out strength and shear strength values are 25% of the ultimate values.
