LARGE DIAMETER SLOTTED TENSION PINS vs. ALTERNATIVE FASTENERS (Bolt/Nut, Groove Pin, Coil Pin)

摘要

The slotted tension pin is a multi-purpose, non-threaded, versatile and economic fastener. Engineers have been quick to utilize the inherent advantages these pins provide in various applications. The cost saving feature of the slotted pins have proven to be a superior fastener application design for years. It is a fastener that not only simplifies design but reduces assembly and production costs. One big attribute of these pins is time-saving because they can be installed in a single operation. The pins have a broad range of applications and design characteristics. The slotted tension pin is tubular in shape, with a longitudinal slot and chamfer to facilitate hole insertion. It is offered in several materials, the most common being high carbon spring steel thru-hardened. The combination of material, hardness, and design provides a stronger joint than many of the mild steel solid pins, taper pins, or grooved pins of like diameter. The ISO 8752 heavy duty and ISO 13337 light duty tension pins have the greatest range of diameters and lengths from 1 millimeter to 50 millimeters in diameter and up to 200 millimeters in length in the standard range. Special lengths up to 250 millimeters can be engineered and ran to order in both the ISO 8752 and ISO 13337. ASME B18.8.2 pins range from a 1/16 to 3/4 diameter. Additionally, parts can be made 7/8 and 1" diameter to 9-1/2" in length. Materials that the parts are made from are high carbon steel, 18-8 stainless steel, 316 stainless steel, A2, A4, and other alloys are available upon request. The pins mostly are utilized plain finish. At Vogelsang Fastener Solutions, we do have a number of customers who request mechanical zinc, black oxide and dip spin platings.
