The 1590MS50TBK is the black version of the 1590 series tamper-resistant screw pack: 50 Torx with Pin screws for imperial 1590 diecast enclosures. It is a natural pairing for black textured enclosures, where the series already supplies black screws to enhance appearance, when you want to keep that look but block removal with an ordinary screwdriver.

These are steel screws with an IP54 rating listed, the same level as the standard 1590 enclosures. Installation and removal use screwdriver bit SCDRIVET10-2, which appears in the same hardware table.

The hardware table ties this pack to a long list of sizes: 1590LLB, 1590LB, 1590H, 1590Y, 1590A, 1590G, 1590G2, 1590S, 1590B, 1590B2, 1590BS, 1590B3, 1590BB, 1590BB2, 1590BBS, 1590Q, 1590U, 1590V, 1590C, 1590T, 1590N1, 1590KK, 1590K, 1590J, 1590XX, 1590X, 1590P1, 1590DD, 1590D, 1590E, 1590F, 1590R1, 1590BX2 and 1590BX. Most enclosures use four screws; the BX, BX2, D, DD, DE, E, EE and R1 sizes need six, and the 1590F needs eight, so one pack can cover several enclosures.

Related packs: 1590MS50T (natural tamper-resistant), 1590WMS50TBK (water-tight, black tamper-resistant) and 1590MS50BK (black Philips head). The pack ships in a bag at 0.11 lbs (0.05 kg) and is RoHS and REACH compliant.
