T-STAR PLUS WAFER HEAD HCR-X™
SPAX® T-STAR plus Wafer Head fasteners with HCR-X™ coating are designed for use in multiple material connections. They are designed with a low profile large diameter wafer head for applications requiring additional surface area under the head.
Design Values & Loads
ALLOWABLE WITHDRAWAL (W) AND HEAD PULL-THROUGH (WH)
- Tabulated withdrawal and head pull-through design values (W) and (WH) are shown at a CD = 1.0. Tabulated withdrawal and head pull-through values shall be adjusted by all applicable adjustment factors per NDS Table 11.3.1.
- Full withdrawal strength is calculated by multiplying the length of thread embedded in the main member by the tabulated reference withdrawal values.
- Head pull-through values for #8 diameter and larger in Southern Pine, Douglas-Fir, Hem-Fir and Spruce-Pine-Fir are minimum 1.5" side member thickness.
- For wood species with an assigned specific gravity between 0.42 and 0.50, use the tabulated values for specific gravity of 0.42. For wood species with an assigned specific gravity between 0.50 and 0.55, use the tabulated values for specific gravity of 0.50. For wood species with an assigned specific gravity greater than or equal to 0.55, use the tabulated values for specific gravity of 0.55.
