National Aerospace Standard(NAS) Socket Head Cap Screws(Lot of 125) NAS1352N3LL12_PCTFE

​The designation NAS1352N3LL12_PCTFE refers to a specific type of aerospace fastener with the following characteristics:​

• NAS1352: This is a National Aerospace Standard (NAS) specification for hexagon socket head cap screws, commonly used in aerospace applications for their reliability and precision.​

• N3: Indicates the screw size and thread pitch. In this context, ‘N3’ typically corresponds to a #10-24 thread size.​

• LL12: Specifies the length of the screw. ‘LL12’ denotes a length of 3/4 inch.​

• PCTFE: Denotes the material of the screw, which is Polychlorotrifluoroethylene. PCTFE is a thermoplastic chlorofluoropolymer known for its excellent chemical resistance, near-zero moisture absorption, nonflammability, and good mechanical properties over a wide temperature range. ​laminatedplastics.com+3Wikipedia+3professionalplastics.com+3

Additionally, the screw features a self-locking mechanism. This is achieved through the incorporation of a Long-Lok® strip, a prevailing torque type self-locking feature that provides excellent vibration resistance. The Long-Lok strip is a universally accepted locking mechanism that ensures the screw remains securely fastened even under dynamic conditions. ​longlok.com

In summary, the NAS1352N3LL12_PCTFE is a #10-24 x 3/4 inch hexagon socket head cap screw made from PCTFE, equipped with a Long-Lok self-locking feature, making it suitable for aerospace applications requiring high precision, chemical resistance, and vibration resistance.
