Sight Screw – Steel – Part #100004615
Lock your zero with confidence. The Sight Screw, Steel (Part #100004615) is a rugged, precision-machined fastener designed to secure handgun and long-gun sights—rear or front—so your point of impact stays put through recoil, training, and the elements. Whether you’re replacing a worn factory screw, completing a slide upgrade, or stocking spares for the armorer’s bench, this steel sight screw delivers dependable clamping force and repeatable alignment.
Why this steel sight screw stands out
Durable steel construction: Heat-treated, high-strength steel resists stripping and head deformation for long service life.
Precision threading: Clean, in-spec threads promote smooth installation and a solid lockup that holds zero.
Secure your zero: Properly torqued, the screw helps prevent sight shift under recoil and hard use.
Finish-friendly head: Crisp drive geometry helps reduce tool slip and protects slide and sight finishes during installation.
Gunsmith approved: A smart replacement or spare part for builders, armorers, and shooters who maintain multiple firearms.
Tip: Use a quality torque driver and a non-permanent threadlocker (e.g., blue) unless your sight manufacturer specifies otherwise.
Ideal use cases
Sight replacement or upgrades: Swap to new irons, fiber-optics, or adjustable rears and secure them correctly.
Maintenance & repair: Replace fatigued or lost screws to restore proper retention.
Range & duty readiness: Keep spares on hand to minimize downtime if a screw loosens or goes missing.
Installation guide (quick steps)
Unload & clear the firearm; verify chamber and magazine are empty.
Degrease the screw and the sight/slide threads with a mild solvent.
Apply a small drop of blue threadlocker to the screw (if recommended).
Seat & torque to the manufacturer’s specification, ensuring the sight is centered/leveled.
Cure time: Allow threadlocker to set before live fire; re-check torque after the first range session.
Compatibility notes
Designed for sight mounting applications; confirm thread size, length, and head profile against your specific sight and slide/receiver.
Commonly used for rear sight bases and some front sight posts; not all platforms share the same specs—verify before ordering.
Care & maintenance
Periodically inspect for loosening after high round counts or heavy carry.
Keep the drive recess clean to ensure proper tool engagement.
Replace any screw that shows burring, stretching, or corrosion.
