Simpson Strong-Tie 5/8″ Drop-In (DIAB) Internally Threaded Anchor

Simpson Strong tie Drop-In anchor (DIAB) that provides easier installation into base materials. Improved geometry in the preassembled expansion plug improves setting capability so the anchor installs with 40% fewer hammer strikes than previous versions. These displacement controlled expansion anchors are easily set by driving the plug toward the bottom of the anchor using either the hand, or power-setting tools. DIAB anchors features a positive set marking indicator at the top of the anchor, Helping you see more clearly when proper installation has take place. 

Use the Simpson Strong-Tie fixed-depth stop bit to take the guesswork out of drilling to the correct depth. The flute design of the top draws away from the hole during drilling, allowing for a cleaner installation

DIAB Manual Installation

1. Drill a hole in the base material using the appropriate diameter carbide drill bit or fixed bit. Drill the hole to the specified embedment. For fixed-depth bits drill the hole until the shoulder of the bit contacts the surface of the base material. Then blow the hole clean of dust and debris using compressed air. Overhead installations do not need to be blown clean.
2. Insert the anchor into the hole. Tap with hammer until flush against the surface
3. Using the designated drop-in setting tool, drive expander plug towards the bottom of the anchor until the shoulder of the setting took makes contact with the top of the anchor. When properly set, four indentations will be visible on the top of the anchor indicating full expansion
4. Insert bolt or threaded rod. Minimum thread engagement should be equal to the nominal diameter of the threaded insert.

OVERSIZED HOLES WILL REDUCE THE ANCHORS LOAD CAPACITY
