The 3/8" 17mm hex socket (18317) is a high-quality socket insert designed for a variety of applications in mechanics and craftsmanship. Made from robust chrome-vanadium steel, this insert offers superior strength and durability that exceeds the requirements of standards DIN 3124 and PN-ISO 1711. A precise hardening and tempering process achieves optimal hardness, extending the product's lifespan. The chrome-plated and polished surface not only provides an appealing look but also protects against corrosion. A special feature is the PRO-DRIVE system, which reduces excessive point loads through specially profiled edges between the working surfaces and protects the edges of screw heads. The hex socket is available in both cardboard packaging and on a hanger, making storage and transport easier.
