1. HOLE SIZE: RECOMMENDED HOLE SIZE IS INDICATED ON EACH DATA SHEET AND IS INTENDED TO BE FOR REFERENCE ONLY. HOLE SIZE MAY NEED TO BE INCREASED OR DECREASED DEPENDING ON BASE MATERIAL, INSTALLATIONTORQUE OR PERFORMANCE REQUIRED. OPTIMUM HOLE SIZE SHOULD BE DETERMINED BY REQUESTING SAMPLES & INSTALLING THEM IN THE INTENDED MATERIAL.
2. HOLE DEPTH: IN THRU HOLE APPLICATIONS THE INSERT LENGTH SHOULD NOT EXCEED THE MATERIAL THICKNESS. IN BLIND HOLE APPLICATIONS THE HOLE DEPTH SHOULD BE 1.2XINSERT LENGTH AND THIS VALUE IS INDICATED ON MOST DATA SHEETS.
3. COUNTERSINK A 60°COUNTERSINK IS REQUIRED FOR MOST MATERIALS TO INSURE A FLUSH SURFACE AFTER INSTALLATION.
4. WALL THICKNESS WALL THICKNESS SHOULD BE 0.35 TO 0.5 X HOLE DIAMETER DEPENDING ON BASE MATERIAL.
