Materials & Heat Treatment General type (PY) Wear Resistance type (PT) NITTUSEIKO IS-F-1 -E_GP The standard material for grooved pins and rivets for general use is low carbon steel wire (SWCH16A, 18A). Grooved pins, grooved rivets, and grooved dowel pins, which especially require wear resistance, are treated with carburizing hardening. • Stainless Steel (PS) Stainless steel (equivalent to JIS SUS304) is recommended when both corrosion resistance and mechanical performance are required. Heavy Duty type (PH) When high mechanical performance is required, alloy steel SAE8630* will be used with providing strength, wear resistance and fatigue resistance through heat treatment. (Standard hardness HRC42-48) * SCM435 will be used for nominal diameter 12mm-20mm. Reduces installation costs/Grooved fastener €-Pin Application Other grooved pins Barb-Lok pin is a fastener to be used in plastic application by pressing installation. 3 barbs located at 120° intervals on the body interferes to mated hole then performs excellent anti-pullout strength. Double Barb-Lok pin has barbs on both ends. NITTOSEIKO CO.,LTD.

Contributes to improved workability and reduced fastening costs, since the pilot hole

Lower installation cost Improved workability Strong self-retaining force Wide variety of typesBefore installation A Standard G-Pin Dimensions Diagram of Groove Expanded Diameter (B) and Pilot Hole diameter (d) When the V-grooves are processed, the materia] in the grooves is raised on both sides, and the outer diameter B of the crest becomes slightly larger than the original blank diameter A. (Fig. 1) Mounting The "G-Pin" is inserted by pressing in the hole specified by the nominal diameter. When Grooved pin is inserted to the hole, the crest is compressed and generates strong radial holding force...
