Product description - Joist Hanger Screw
The screw for construction fittings.
Drive
- optimal torque transmission
- tight, snug fit and fast centering
- no tumbling motion
- no "come out" effect of the bit
Head Shape
Pan Head
- more surface pressure by a large contact area
- pleasant apperance due to rounded form
Reinforced Shank
- shank diameter is adapted for drill holes of the joist hanger
- positive-fit connection
- perfect fit
Asymmetrical Thread
- reduced drive-in torque
- high overtorque
- quicker screwing-in than common screw
- high withdrawal force
Tip
- perfectly formed tip allows positioning with utmost precision
- counter thread
- reduction of the screw-in torque
- reduced splitting in close to edge applications
- through the die cutting effect of the ring thread blow-outs are largely avoided
Note
Galvanized screws are not suitable for the outdoor area and for rooms which are exposed short-term or constantly to high humidity. Especially developped for the connection of sheet steel at derived timber products and solid wood products.
