2.5 X 10 mm Stainless Steel Hex Socket Flat Head PT Thread Screws for Plastic

Flat Head PT@ Thread Screws

Harden material

Hex Drive

Wider thread distance

Flat head PT@ thread screw is also known as Thread forming screw , it has a wider pitch and thinner threads compared to common tapping threads , this design increases shear areas and support a more good material flowing performance when it is installed .

Key Characteristics

◆ Harden material

◆ High tensile strength

◆ Fast thread drilling performance

◆ Good material flowing performance

◆ High clamping load performance

◆ Reduce radial stresses

PC	d	0.85d	2d
PA	d	0.75d	1.7d
ABS	d	0.8d	2d
ASA	d	0.78d	2d

Installation

1 . Drill a pre-hole in material with pre-depth for screw ( see details in table )

2 . Insert screw into hole and screwing it in a wrench .
