          CL801 Series Inserts

          The advantages: 
          Series CL801 Precision Machined-Headed Brass:The CL801 headed brass
          Compression Limiters are the same as the CL800 with the addition of a head.
          Similar to the CL601,the head provides extra bearing surface on the mating
          component when a flanged bolt or a washer is not used.            

          A properly designed bolted joint must meet the following criteria:
          The head of the bolt, or washer if one is used, should always seat against both theplastic host and the Compression Limiter under load. This will prevent deterioration ofthe bolted joint resulting from diminished clamping load due to plastic creep.
          The rated proof load of the Compression Limiter should be equal to or greater thanthe proof load of the bolt to assure that the Compression Limiter will not yield prior tothe bolt under excessive clamping loads.
          The mating component that the Compression Limiter seats against should be strongenough to withstand the localized compressive stresses generated by the clampingforce.
          The clearance between the maximum bolt diameter and the minimum installed insidediameter of the Compression Limiter should be sufficient to compensate for expectedassembly tolerances.

          CL801 Brass Bolt Insert Threaded data

          Q1: What is the Series CL800 Compression Limiter and how is it manufactured?
          A: The Series CL800 is a precision-machined compression limiter made from 360 brass. Like the CL600 series, it can be either molded-in or pressed into an assembly during manufacturing.

          Q2: How does the CL800 differ from the aluminum CL600 series?
          A: While both serve similar functions, key differences include:

          • Material Properties: Brass has lower yield strength than aluminum, requiring thicker walls to accommodate the same class/grade of bolt

          • Size & Weight: Brass limiters are larger and heavier than equivalent aluminum versions

          • Bearing Surface: The thicker wall provides increased bearing surface for mating components

          • Galvanic Properties: Brass is more noble on the galvanic series, reducing corrosion concerns in certain applications

          Q3: Why would a designer choose brass over aluminum for compression limiters?
          A: The primary reasons include:

          • Galvanic compatibility requirements (brass is more noble on the galvanic series)

          • Applications where additional bearing surface is beneficial

          • Environments where brass's corrosion resistance is advantageous

          Q4: What are the key design criteria for proper bolted joint performance?
          A: Four critical criteria must be met:

          1. Proper Load Distribution: Bolt head/washer must contact both plastic host and compression limiter to prevent plastic creep

          2. Strength Compatibility: Limiter's proof load must equal or exceed the bolt's proof load

          3. Component Strength: Mating component must withstand localized compressive stresses

          4. Dimensional Tolerance: Adequate clearance must exist between bolt diameter and limiter ID for assembly variations

          Q5: What is the maximum bolt specification for the CL800 series?
          A: The CL800 is rated for use with bolts up to ISO Class 10.9/Grade 8 specifications.

          Q6: How does the compression limiter prevent joint deterioration?
          A: By ensuring the clamping load is carried through the compression limiter rather than the plastic material, it prevents:

          • Plastic creep under sustained load

          • Loss of clamping force over time

          • Joint loosening and potential failure

          Q7: Can the CL800 be used in both molding and press-fit applications?
          A: Yes, the CL800 is designed for both molding-in during plastic part manufacturing and for press-fit installation in existing assemblies.
