6-32 x 1/2 T15 RMR to Glock Gen 6 ORS screws (package of 4).
Note these will not work with Glock Gen 3 to Gen 5 MOS RMR-to-plate, MOS RMR screws are shorter (6-32 x 3/8), and can be found here: RMR to MOS plate mounting screws
The 6-32 x 1/2 screws are incompatible with Holosun 407C and 507c series sights, for more information, please visit this page: RMR sight to plate screws vs. Holosun screws
Among other improvements Glock has made for its Gen 6, the longer 6-32 and M4 screw holes are noteworthy for optics users. Longer sight-to-slide screws serve to distribute stress over a longer length (better load distribution), more thread engagement also helps the optics stay in the ORS pocket better in adverse conditions.
There is no substitution for a meticulously engineered and QCed steel plate with tight tolerances like OPF-G6, RMR for defense and duty use (we discourage aluminum plates that barely have s tensile strength than polymer plates), the longer screws do help duty grade, as well as loosely toleranced, low tensile strength plates, they have the unintended consequence of helping to disguise a lesser plate's shortcomings. Longer screws are not the solution for plates with loose tolerances made in unsuitable materials.
Package of 4, includes a packet of Vibra-tite VC-3.
Drive size: T15
Countersink angle: 82 degrees, compatible with RMR, RMR HD, and SRO.
Tensile strength: 140,000 PSI
Hardness: Rockwell C39
Sight-to-slide torque value: 13 to 15 in lb.
Made in USA.
Why do screws cost $9.50 (and more when USPS raises its rates again)?
Screws aren't expensive, a Vibra-tite VC-3 packet costs nearly $1 each, but these aren't the biggest factors for the relative high cost, shipping is. We can't ship screws in USPS letter as the screws invariably break through the thin envelope, and the VC-3 packet can be crushed and leak, they must be shipped via USPS or UPS large package / thick envelope that can range from $6 to $8.
The replacement screws we have on our site are mostly provided as a service, there is little to no profit for us. Agency armorers, please contact us re: obtaining or ordering the screws in bulk.
Sight-to-plate, and sight-to-slide screws are consumables in a high stress, high G, and unforgiving environments, as is the case in this application. Threads are under tension when they're torqued to spec, more so when users over torque them. Federal, state, and local law enforcement agencies rarely re-use screws, and armorers replace them either after each battery change (with RMR) or on a scheduled basis.
