Simpson Strong-Tie ECCQ End Column caps provide a high-capacity connection for column-beam combinations. This design uses Simpson Strong-Tie Strong-Drive SDS Heavy-Duty Connector screws to provide faster installation and provides a greater net section area of the column compared to bolts. The SDS screws provide for a lower profile compared to standard through bolts. The Strong-Tie ECCQ46SS-SDS2.5 post base features a Gray Paint finish for added corrosion resistance and requires the use of hot-dip galvanized fasteners which meet the specifications of ASTM A153.

• Install 1/4"x2 1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap. (Lag screws will not achieve the same load.)
• CCOQ and ECCOQ column cap only (no straps) may be ordered for field-welding to pipe or other columns. Dimensions are same as CCQ and ECCQ.
• For rough-cut lumber sizes, provide dimensions. An optional W2 dimension may be specified with any column size given. (Note that the W2 dimension on straps rotated 90° is limited by the W1 dimension.)

NOTE: The correct fasteners installed in the correct position must be used to achieve published load values

California Residents: WARNING

•The SDS screws provide a lower profile than standard through bolts
•Certified welds for confidence in strength and loading
•Uplift loads have been increased for earthquake or wind loading
•Diamond holes for temporary fastening

•Fasten with 1/4" x 2 1/2" Strong-Drive SDS Heavy-Duty Connector screws, which are provided with the column cap. (Lag screws will not achieve the same load.) Use stainless-steel Strong-Drive screws with stainless-steel connectors.
•For rough-cut lumber sizes, provide dimensions. An optional W2 dimension may be specified with any column size given. (Note that the W2 dimension on straps rotated 90° is limited by the W1 dimension.)
