Low-Strength Steel Hold-Down Bolts
Round
Flat
About half the strength of medium-strength bolts, these bolts are for light duty work-holding. They’re often used to hold batteries in place and have a hook on one end that grabs as the other end is tightened with a nut. The zinc plating provides corrosion resistance in wet environments.
