ATLAS® Blind threaded inserts are designed to provide strong threads in thin panel sections. They are called “blind” because they can be installed from one side of the panel. Access to both sides is not required. This convenient feature makes these fasteners ideally suited for tubing, extrusion, and other similar types of applications.
There are four types: SpinTite®, ATLAS® FM™, MaxTite®, and Plus+Tite® fasteners.
The SpinTite® types are used for most applications where strong threads are required for blind applications. They are installed from one side using a spin-spin technique. In addition to high thread strength and torque-out, these fasteners have minimal inventory requirements since each size can accommodate many grip ranges (material thickness).
The ATLAS® FM™ inserts have metric threads and dimensions and install into metric size round or hex holes to meet European design standards. These inserts are installed using “spin-pull” or “pull-to-pressure” installation tools.
The heavy duty MaxTite® types are designed for the most demanding applications. They are installed from one side using “spin-pull” or “pull-to-pressure” installation tools.
The blind Plus+Tite® inserts feature a slotted body that folds into four petals upon installation, gripping the backside of the parent material. These inserts can be installed into single, variable, or multiple thickness materials.

Picking the insert
Installation Tooling
As with all air tools, the correct air pressure is critical to proper operation. Air pressure regulators are always recommended. 90-100 psi is the recommended maximum pressure for all tools. Please see the ATLAS catalog for recommended air pressures for our spinspin tools. The spin-pull and pull-to-pressure tools should always be operated in the range of 85-100 psi.
Air tools in a manufacturing environment will wear and need repair from time to time.
ATLAS tools have a one-year warranty for manufacturing defects. Parts and labor are covered.
When a very large number of inserts need to be installed repetitively, the use of robotics or automation may be necessary. Please contact us to discuss the application details and possible custom solutions.
Mating part/bolts
Installation holes for ATLAS blind rivet nuts should be aligned to parent material to ensure a uniform backside formation. The hole size should meet the product tolerance and specification. The mating part should contact the head of the blind rivet nut to ensure optimum torque performance of the joint.
The mating screw should be Grade 5 or Metric Class 8.8 strength. ATLAS blind rivet nuts are designed to meet the torque, tensile and clamp load of the mating fasteners. Thread fit may be 2A, 3A or Metric 6G design. The mating screw thread length should engage all threads of the blind rivet nut to ensure optimum torque strength.
If an application requires a mating screw with a nylon patch, adhesive, or other thread locking mechanism, a hex body blind rivet nut in a hex hole will be needed to resist the prevailing torque created by the locking mechanism.

TORQUE STRENGTH DATA - TORQUE-AXIAL LOAD RELATIONSHIP
When used with a non-rotating mating part, these fasteners may be safely loaded to a torque equivalent of their maximum upset loads. Surpassing these loads will cause the screw to break, or the fastener will continue to upset until ultimate strip load is attained.
Because of the many variables such as type of lubrication, plating, type and grade of screw or bolt, it is recommended that a pilot test be conducted to determine the optimum application torque.
