Stainless Steel Screws and Hardware

Reliance stainless steel fasteners are manufactured from A4-70 cold worked austenitic stainless steel, certified to a minimum of 700MPa tensile strength, while providing the best possible corrosion resistance. Thread sizes from M1.6 to M10 are available. In addition to our standard machine screws and set screws for special applications we also offer:-

  • Captive screws - socket head cap screws to ISO 4762 with plain shank for captive assembly of screw to prevent fastener loss, ideal for service covers. Available in sizes M2 to M6. 
  • Ventilation screws - socket head cap vented screws to ISO 4762 drilled through on axis. Mainly used in the clean room outgassing chamber environments in high vacuum equipment and other clean critical applications. Available in sizes M2 to M6. Rolled thread for excellent surface finish, superior thread strength and increased hardness properties.
  • Wire locking screws - plain socket head cap screws to ISO 4762 with cross drilled head to allow fastener retention by wire locking. Rolled thread for excellent surface finish, superior thread strength and increased hardness properties.
  • Shoulder screws - socket head screws with accurate diameter shoulder for precision assemblies. Maybe used to replace components such as shafts, pivots, pins and guides. Ideally used for linkages and stationary guides.
  • Plain socket head screws - rolled thread for excellent surface finish, superior thread strength and increased hardness properties.
  • Pan head and cheese head machine screws
  • Countersunk machine screws
  • Solder tip set screws - stainless steel set screws (also known as grub screws) with a semi-soft solder tip which helps prevent marking on the shaft.
