    Steel Cup-Tip Set Screws

    Image of Product. Front orientation. Set Screws. Steel Cup-Tip Set Screws.
    Made of alloy steel, these screws are strong enough to hold components without wearing down. The tip has thin edges that dig into surfaces for a secure hold. They often lock gears, pulleys, and other transmission components onto shafts.

    Steel Flat-Tip Set Screws

    Image of Product. Front orientation. Set Screws. Steel Flat-Tip Set Screws.
    Spread out holding power and protect surfaces from damage. Unlike cup and cone tip screws, the flat tip on these distributes pressure evenly, reducing marring but not holding as tightly. They're a good choice for repositioning parts frequently on jigs, fixtures, and other applications where the tip presses against a flat surface. Made of alloy steel, these screws are strong enough to hold components without wearing down.

    Stainless Steel Flat-Tip Set Screws

    These corrosion-resistant screws spread out holding power and protect surfaces from damage. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. Unlike cup and cone tips, the flat tip distributes pressure evenly, reducing marring but not holding as tightly. They're a good choice for repositioning parts frequently on jigs, fixtures, and other applications where the tip presses against a flat surface.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.

    Keep pressure consistent on workpieces that aren't fully flat or parallel. A rolling ball on the tip of these screws maintains contact and swivels 360° to make small adjustments without loosening. Made of alloy steel, they are strong enough to hold components without wearing down.

    Tighten these screws to locate and hold components without worrying about your sockets slipping. Four large, flat sides give you reliable torque but slightly less than external hex drives. Like a dowel pin, the tip slides into mating holes on shafts, tubing, and other surfaces. Made of alloy steel, they're strong enough to hold components without wearing down. Also known as half dog-point set screws.

    Long-Nose Spring Plungers

    Lock heavy moving parts securely in place. Often used in indexing applications, these have a longer nose than ball-nose spring plungers to withstand greater side forces without disengaging. The nose compresses when a part presses against it, and then pops out into deep notches or grooves for a strong hold.
    Spring plungers are available with or without a threadlocker. Those with a threadlocker won't wiggle loose from vibration. Spring plungers without a threadlocker are easier to remove.
    Steel Nose—The strongest, most wear-resistant noses, these won't deform from stress and vibration. Steel is best for dry environments, however, since moisture will cause it to rust.

    Punch large parts free from presses or dies with a nose that’s three times longer than others. These spring plungers also have a long spring that doesn’t need to compress as far to retract the nose, so it can handle high speed, repetitive ejecting jobs without wearing down.
