Review on Hillman 180294 Pronged 10 Inch 100 Pack by Tony York

Tees are available in 3, 4 and 6 prongs. The triangular nut is designed for use in hardwoods where fewer teeth reduce the risk of damaging the wood. Hex tees are designed for soft woods (like plywood, fiberboard, etc.) for better grip. 4 prong tees are designed for hard or soft wood. Other websites describe it that way. "T-Nuts are available with 3, 4 or 6 teeth, each with their own benefits. Typically, 3-tooth nuts are used for plywood, 4-tooth nuts for hard or soft woods, and 6-tooth nuts for softer materials and materials. composite materials”. The photo clearly shows this is a 4 pin tee and the description says it is hardwood or softwood, consistent with the descriptions elsewhere and the photo. Got 3 and will be back for a refund.
