Streamlight TLR 7, 8, 9 & VIR HEAVY-DUTY MOUNTING SCREW KIT
This upgrade mounting-screw kit allows you to snug your TLR-7, TLR-8, TLR-9 or TLR-VIR tight. Replaces the slotted factory screw shown in the last photo, will fit all models that use that same factory screw. The factory screws are difficult to tighten due to the shallow/curved slot which gets marked-up and rounded-out easily. This kit is shipped in a packet containing one alloy-steel socket screw, one over-sized washer and a hex wrench. You can use the original spring from your factory screw assembly or mount it without the spring. Finger-tight using the included wrench or torqued to 10 inch-pounds is perfect, too tight and you may damage the mount, at 10 inch-pounds it's rock-solid.
