Drop-in Anchor Bolts

Drop-in Anchor Bolts
Product Details

A Drop-In anchor consists of a tubular expansion shield and a solid, cone-shaped expander plug. The expander plug is case hardened and tempered to prevent galling and binding during expansion. The shield has four equally spaced slots for a portion of its length, the bottom part may be knurled. The shield also has a smooth, flangeless top that allows either flush or countersunk installation. the bottom lip of the shield is tapered to allow maximum depth and holding power.
