2020 Series Aluminum Extrusion (European Standard) #
- Profile Dimensions: The 2020 series aluminum extrusion typically has a square cross-section of 20mm x 20mm. This measurement refers to the external dimensions of the profile.
- T-Slot Dimensions: The T-slots in a 2020 profile are designed to accommodate M5 bolts. The exact dimensions of the T-slot can vary slightly between manufacturers, but they are generally made to fit standard M5 T-nuts or slide-in nuts.
- Wall Thickness: The wall thickness of 2020 aluminum extrusions can vary, but a common range is around 2mm. This thickness affects the profile’s strength and rigidity.
80/20 10 Series Aluminum Extrusion #
- Profile Dimensions: The 80/20 10 Series profiles are based on the imperial system and have a 1-inch x 1-inch square cross-section. The exact dimensions would be approximately 25.4mm x 25.4mm if converted to metric, but these profiles are specifically designed and referred to in inches.
- T-Slot Dimensions: The T-slots for the 10 Series are designed to work with 1/4-20 bolts, which are standard in the U.S. The slot dimensions are tailored to fit these bolts and the corresponding T-nuts designed for the 10 Series profiles.
- Wall Thickness: Similar to the 2020 series, the wall thickness for the 10 Series can vary by manufacturer. However, a typical range is around 0.075 inches (approximately 1.9mm), providing a balance between weight and structural integrity.
