Holey Tube Technical Data
Click on the profile to view tech sheet:
Extruded HT Series profiles are structured around 1.50" square tubes and feature 1.50" flanges in various configurations. Each of the profiles are available with prefabricated holes along 1.50" centerlines, or without any machining at all.
Q. The prefabricated HT Series™ has what diameter of mounting holes?
A. .328" Click Here for Prefabricated Machining Detail
Q. What interval are the HT Series™ mounting holes are evenly spaced at?
A. 1.50" Click Here for Prefabricated Machining Detail
Q. If the pre-manufactured hole pattern is based on 1.50" intervals, is my cut length required to be in 1.50" increments?
A. No. If you require your cut length to be something other than an increment of 1.50", you can cut HT Series™ tube without holes to length and call out 7246 drill services, or use prefabricated HT Series™ tube with an Extended Tube Insert.
Q. To properly apply a Standard Tube Insert, what is the distance from the end of the extrusion to the center of the first mounting hole?
Q. What are the basic methods for making an HT Series™ connection?
A. Standard Inserts with Flanged Hex Bolts, Standard Inserts with Spring Roll Pins, and Joining Plates
Q. How many different profiles of HT Series™ extrusions are offered?
A. Five profiles with various flange configurations. In addition to the square tube profile, 80/20 also offers a single flange "P" profile, a double flange "A" profile, a single flange "T" profile, and a double flange "H" profile.
Q. What is the alloy and finish of the HT profiles?
A. HT Series™ profiles are extruded from 6105-T5 Aluminum and have a clear 204-R1 anodized finish.
Q. What is the alloy and finish of the Standard Tube Inserts?
A. All inserts offered from 80/20 are 6105-T5 Aluminum and are mill-finish.
Q. What other series of 80/20 is HT Series™ most compatible with?
A. Nearly all 15 Series parts and components are compatible with HT Series™.
Q. What is the cut to length tolerance for HT Series™ profiles?
Q. What are the proper tools needed to insert spring roll pins?
A. Hard/Soft Face Hammers work great for driving Spring Roll Pins and won’t damage the surface of the HT Series™ profiles. Also, using a Roll Pin Punch simplifies keeping the Spring Roll Pin aligned with the HT Series™ through hole.
Q. How do I specify through hole machining services for HT Series™ profiles?
A. Machining Services for HT Series™ profiles are specified by calling out the service, the axis that the service goes through, the style or dimensional location, and the end the service is from.
Q. What wrench sizes are needed to put HT Series™ profiles together?
A. 5/16-18 Hex Bolts and Nuts require a ½" open end wrench and M8 x 1.25 Hex Bolts and Nuts require an M13 open end wrench.
Q. What are the stock lengths for HT Series™ profiles?
A. All HT Series™ profiles are available in 97" and 145" lengths.
