May 28, 2019 - Titan Tool Supply Inc., Buffalo, New York, announced the introduction of its new line of precision Diamond and Borazon micro-finishing grinding pins. They are designed to meet an increasing demand for small precision ID grinding in industries such as ceramics, electronics, mold-making, and tool-and-die-making. A carbide shank provides added strength and precision, according to Titan Tool Supply.

The working ends of the pins are coated with either Diamond or Borazon. Three diameters are offered for use in small openings. These include 0.016 in. dia. with 500/600 grit; 0.020 in. dia. with 325/400 grit; and 0.024 in. dia. with 325/400 grit.

June 4, 2018 - PEM® TSO4™self-clinching threaded standoffs from PennEngineering offer reliable fastener solutions to securely stack or space components in ultra-thin stainless steel assemblies. These hardened stainless steel fasteners clinch into stainless sheets as thin as .025 in. / 0.63mm and become permanent parts of an assembly. The standoffs ultimately will reduce the amount of required hardware in an assembly, promote thinner and lighter designs, and minimize typical handling issues associated with loose hardware.

Among unique design features, the fastener’s thread design at the barrel end minimizes the length for a mating screw. Shorter standoffs are typically thru-threaded and longer standoffs are blind. Thread-type variations with a thicker wall can further be specified to provide increased bearing surface for the mating component or panel. For applications in potentially corrosive environments, an optional nickel plating can be added for excellent corrosion resistance.

PEM TSO4 standoffs are available in thru-threaded or blind threaded versions and in a variety of lengths and several standard thread sizes (#2-56, #4-40, and #6-32 / M2.5, M3, and M3.5). They are manufactured from hardened 400 Series stainless steel for use in stainless sheets with maximum hardness up to HRB 88 on the Rockwell “B” scale or HB 183 on the Brinell scale.

The standoffs mount simply and quickly by pressing the fastener into a round hole in the host sheet and applying sufficient squeezing force using a standard press to embed the standoff’s head flush in the sheet and complete the process. A single mating screw completes the attachment process.

May 9, 2018 - New stainless steel PEM® TK™TackSert® pins from PennEngineering introduce ideal alternatives to screws for attaching thin panels in assemblies. They can securely attach panels of any material to base panels manufactured from common casting materials (such as AZ91D) or plastics (such as ABS and printed circuit boards). Unique design features promote reliable performance in service.

PEM TK TackSert pins deliver multiple advantages over screws by eliminating any need for mating threads from tapped holes or inserts and the rework frequently required due to screw cross-threading and driver bit “cam-out.” Patches intended to prevent fastener loosening in service are unnecessary.

Among pin design features, a tapered tip assists in pin location to enable easier alignment into a base panel, a specially engineered diagonal broaching knurl (instead of threads) creates a firm interference fit without hole-tolerance issues, and a low-profile head minimizes protrusion on the attached panel.

The pins are offered in a variety of lengths and can successfully attach sheets with thicknesses from .067 in. / 1.7mm to .185 in. / 4.7mm, depending on pin length.
