Installation tips
- 1.Drill a 5/8" hole for a 1/2" drop-in — never use an undersized bit
- 2.Use a rotary hammer for clean 5/8" holes — required for proper anchor seating
- 3.The setting tool must bottom out fully — partial setting dramatically reduces capacity
- 4.For overhead/suspended loads, apply a safety factor of 4:1 minimum
- 5.Stainless steel versions required in food processing or chemical environments
