Our take on the Simpson Strong-Tie Wafer-Head Wood Screw SD8X1.25 - #8 x 1-1/4 In, 100 Count

The Simpson Strong-Tie SD8 is a #8 x 1-1/4 in wafer-head structural wood screw with a T25 star drive and a clear zinc coating. The wafer head sits low and flat, and the star drive takes high torque without cam-out, which is why these are common in joist hangers, deck hardware and composite-to-wood fastening. They are a step up from generic drywall or deck screws for load-bearing connectors, though the small 1-1/4 in length limits them to thin material and shallow connections. Buyers pick them for consistent quality and the 100-count box that covers a full hardware install.

What reviewers say

Owners and builders rate these screws for reliable driving and low cam-out with the T25 bit. Most complaints center on the short length and the coating being lighter than hot-dip galvanized for harsh outdoor use.

  • Head profilePraisedThe wafer head sits low and flat against hardware.
  • LengthCriticisedAt 1-1/4 in it is too short for thicker lumber and deeper connections.
  • CoatingMixedClear zinc holds up indoors and in light weather but not in severe exposure.

Questions and answers

What is a wafer-head screw used for?
Wafer heads have a wide, low profile that clamps hardware and thin material flat, such as joist hangers, brackets and composite decking. They are not meant to countersink flush like a flat head.
Do these need a special bit?
Yes. They use a T25 star driver bit, which is not the same as a Phillips or square bit. Using the right bit is what gives the low cam-out these screws are known for.
Can I use them outdoors?
The clear zinc coating is rated for exterior use, but it is not hot-dip galvanized. For coastal or constantly wet conditions, a heavier-coated or stainless fastener is the safer choice.
Will they work for light-gauge steel?
Simpson lists them for light-gauge steel connections as well as wood and composite. The self-drilling point and star drive help them bite into thin steel.
How many screws come in a box?
Each box contains 100 screws, enough for a full hanger or bracket install but not a large deck.
