Q
Clarence, guest, from IA, United States, asked on November 07, 2024

Will these screws work to mount CT1550 to a hellcat?

Manufacturer Answer
A

The Ultimate Red Dot Screw Pack includes the common M4×0.7 screws typically used for Hellcat optic installations and should contain a compatible option. As always, proper screw length and thread engagement should be verified during installation to ensure a secure fit without bottoming out in the slide.

Yes. The Ultimate Red Dot Screw Pack includes a wide variety of common optic mounting screws and should contain the screws needed for mounting a Holosun 507K to an optics-ready S&W Shield Plus. As always, verify proper thread engagement and screw length during installation before final tightening.

The Holosun 407K should come with screws to fit the Taurus GX4 TORO. Please email us at techsales@opticsplanet.com regarding your question.

This Swampfox Ultimate Red Dot Mounting Screw Pack contains 15 four-screw sets of various thread pitches and lengths. These small-head, T10 screws are the most likely to be the “problem solvers” needed to attach Kingslayer, Liberty, Justice, and Sentinel to those slides and mounts. Five sets of Do-It-Yourself screws (6-32, 4-40, 6-40, M3, M3.5, M4 pitches) deliberately feature a too-long-for-everything 14mm effective thread length. Small heads: all heads 5.0 mm diameter except #6-32 specs (5.5 mm diameter).
