Final answer:
To replace an IFA 2024 rivet with a 2117 rivet, confirm the 2117 alloy's suitability, measure the diameter of the hole, and determine the required rivet length by the grip length of the materials being joined. Use a rivet manufacturer's sizing chart for an exact match.
Step-by-step explanation:
When replacing an IFA 2024 rivet with a 2117 rivet, it's important to determine the correct size based on the specifications of the application. The 2024 and 2117 designations refer to different aluminum alloy compositions with different strength characteristics. The first thing to consider is whether the 2117 rivet will provide the necessary strength for the application, as it typically has a lower shear strength than the 2024 rivet.
Once you have confirmed the suitability of the alloy, sizing the rivet properly involves measuring the diameter of the hole left by the old rivet. The new rivet should closely match this diameter to ensure a tight fit and maintain the integrity of the structure. Additionally, the grip length of the rivet, which is the combined thickness of the materials being joined, should be measured accurately to determine the required length of the new rivet. Rivet manufacturers provide sizing charts that can assist in selecting the right diameter and length based on these measurements.
