Who is the Pachmayr Master Gunsmith 277 Piece Screw Kit for?

  • Professional gunsmiths and armourers servicing American firearms — requires a broad selection of standard imperial fasteners, providing 12 pieces across 7 lengths of #6-48 fillister and oval screws, 3 lengths of #8-40 screws, and dedicated #10-32 plug screws in a single gunsmithing screw assortment kit.
  • Firearm owners performing DIY scope mount and sight installations — provides 277 pieces of blued steel hardware, including 3 distinct lengths of #8-40 fillister and oval head screws (3/16", 1/4", and 3/8") to securely mount optics bases or replace damaged factory sight fasteners at home.

Less suitable for: Firearm platforms that use metric threads such as M3.5 or M4, or high-volume commercial repair workshops that exceed the 12-piece per variant capacity limit; these scenarios require metric fastener kits or single-size bulk hardware packages.
