What are captive panel retainers?
Captive panel retainers are fasteners explicitly designed to secure metal panels or thin materials in situations requiring frequent access. The Amatom brand offers captive panel retainers that aim to minimize the number of components, thus reducing the likelihood of loose hardware that may potentially harm other elements. These retainers consist of various components crafted from stainless steel, aluminum, hardened carbon steel, brass, or plastic, with the material choice depending on the project's application and strength demands.
A Guide to Amatom’s Captive Panel Retainers
Designed to be used in conjunction with type 1 captive screws, Type 1 captive panel retainers are made from SS corrosion-resistant steel (stainless steel) following the specifications of ASTM A581-75 for sizes up to 1/2 O.D. and AMS-5762 for sizes over 1/2. They are also available in B brass, complying with QQ-B-626 Comp 22 1/2 Hard. The SS retainers undergo passivation per QQ-P-35 to enhance their corrosion resistance, while the brass retainers are nickel-plated to QQ-N-290 Grade G. The threads on these retainers adhere to the standards of UNC-2B and UNF-2B. The production of these retainers meets high precision standards regarding workmanship and follows the quality control guidelines outlined in MIL-STD-105. They are specifically manufactured for use with government equipment.
These retainers, which are made from SS corrosion-resistant steel (stainless steel) to ASTM A581-75 specifications up to 1/2 O.D. and AMS-5762 for sizes over 1/2, and B brass to QQ-B-626 Comp 22 1/2 Hard standards, are specifically used with type 2 captive screws. The SS retainers are passivated per QQ-P-35 for boosting corrosion resistance, while the brass retainers are nickel-plated to QQ-N-290 Grade G. Made with high precision and checked under MIL-STD-105, the retainers, namely Type 2A, 2B, 2C and 2D panel retainers, are specially designed for government use.
Panel Retainers of types 3 and 3A have been fabricated out of stainless steel (SS corrosion-resistant steel) and B brass, designed primarily for use with type 3 captive screws. ASTM A581-75 specifications have been used to manufacture retainers up to 1/2 O.D., while AMS-5762 has been employed in retainers above the mentioned size. Besides being coated with QQ-P-35 for corrosion resistance, the SS retainers have also gone through passivation per QQ-P-35 for increased security. On the other hand, the Brass retainers have been nickel-plated up to QQ-N-290 Grade G. To attain their uniform quality, these panel retainers have gone through precision workmanship and the quality controls laid down by MIL-STD-105. Like the other panel retainers mentioned above, these type 3 retainers are designed for government use.
