    Change thread sizes or types, such as fine to coarse threads, on parts without changing gender. These adapters can also be used as standoffs to position components in assemblies and to create space between parts. They have an external hex, so you can tighten them with a wrench.
    18-8 Stainless Steel—18-8 stainless steel adapters resist corrosion in wet environments but will corrode when exposed to salt water and chemicals. They may be mildly magnetic.
    316 Stainless Steel—316 stainless steel adapters are for use in wet environments and have the best corrosion resistance. Unlike 18-8 stainless steel adapters, they resist corrosion caused by salt water and chemicals. They may be mildly magnetic.
    ASTM A276 and ASTM A582—Adapters that meet ASTM specifications are made from or plated with materials that adhere to specific standards for chemical and physical properties, such as hardness.

    Change inch threads to metric with these adapters, or swap metric threads for inch. An external hex lets you tighten or loosen them with a wrench. You can also use them to increase or reduce your thread size, or to create space between parts in an assembly.
    18-8 Stainless Steel—18-8 stainless steel adapters can be used in wet environments, but chemicals or salt water will cause staining and rust spots.
    316 Stainless Steel—For areas exposed to salt water or chemicals, 316 stainless steel adapters are the best choice. Only harsh chemicals, such as hydrochloric acid, will cause them to corrode.
    ASTM A276 and ASTM A582—Adapters that meet ASTM specifications are made from or plated with materials that adhere to specific standards for chemical and physical properties, such as hardness.

    Connect two differently sized male-threaded parts, such as threaded rods, and tighten with a standard wrench. The threads on these adapters have various sizes and spacing, so you can increase or decrease thread size or adapt from coarse to fine threading. You can also use them to change the gender of a connection from male to female. Small adapters can work as threaded standoffs, which position and separate circuit boards and other components in assemblies.
    18-8 Stainless Steel—18-8 stainless steel adapters withstand wet environments but will corrode when exposed to salt water and other chloride solutions.
    316 Stainless Steel—316 stainless steel adapters are ideal in wet environments and will not corrode when exposed to salt water or harsh chemicals.
    ASTM A276 and ASTM A582—Adapters that meet ASTM specifications are made from or plated with materials that adhere to specific standards for chemical and physical properties, such as hardness.

    Need to join two female-threaded parts, such as coupling nuts, with dissimilar inch thread sizes? Attach them to these adapters and tighten the exterior hex nut for a secure connection. You can also use these adapters to change the gender of a mating part from female to male, increase or decrease the thread size, or convert the threads from fine to coarse (and vice versa). The smaller adapters act as threaded standoffs, positioning and separating circuit boards and other components in assemblies.
    18-8 Stainless Steel—18-8 stainless steel adapters resist corrosion caused by water. They're good for wet and damp environments but will corrode when exposed to salt water and other chloride solutions.

    Adapt threaded rods from inch to metric. These adapters connect two male-threaded fasteners, so you can change the gender of a mating part or increase or decrease its thread size. The hex-shaped body fits into the head of a standard wrench. Small adapters can also be used as standoffs, positioning and separating circuit boards and other components in assemblies.

    Screw-Locking Seize-Resistant Key-Locking Threaded Inserts for Soft Metal

    Image of Product. Bottom orientation. Threaded Inserts. Screw-Locking Seize-Resistant Key-Locking Threaded Inserts for Soft Metal.
    Create the tightest hold in aluminum and other soft metal without screws sticking. The lubricant on these inserts eases installation, and the irregularly shaped threads won’t let screws back out from vibration. Inserts have keys that drive into material to prevent them from slipping or rotating in the hole.
    To install, drill and tap a hole in your material. Then, thread the insert onto the installation tool and screw it into the hole. Place the tool over the keys and hit it with a hammer to drive them in.
    Thin Wall—Use these inserts near the edge of workpieces or wherever you only have space for a small hole. They're also lighter than standard and extra-thick wall inserts for applications with strict weight limitations.
    Dry-Film-Lubricated 18-8 Stainless Steel—The choice for wet and outdoor environments, these inserts resist rust and mild chemicals.

    Smoothly install these inserts for strong threads near the edges and corners of soft metal surfaces. They’re lubricated to prevent sticking as you thread them in. Since these have thinner walls than our key-locking and thread-locking inserts, they don’t need as much space and won't bulge or crack the material. The knurls press (swage) into the material to keep inserts in place when you tighten or loosen a screw.
    To install these inserts, you need a drill bit, a counterbore, a standard tap, an installation tool, and a hammer. Drill a hole, counterbore the top, and tap it. Place the insert into the installation tool, then hand-tighten it into the tapped hole. Strike the tool to secure the insert and drive the knurls into the surrounding material.
    High-Strength Dry-Film-Lubricated Cadmium-Plated Alloy Steel—Stronger than our 17-4 PH stainless steel inserts, these inserts absorb impact without cracking and stand up to high-pressure applications. The cadmium plating prevents corrosion in wet environments.

    Add strong threads to the edges of soft metal without bulging or cracking the material. These inserts have thinner walls than our key-locking and thread-locking inserts, so they don’t need as much space around them. The knurls press (swage) into the material to keep inserts in place when you tighten or loosen a screw.
    To install these inserts, you need a drill bit, a counterbore, a standard tap, an installation tool, and a hammer. Drill a hole, counterbore the top, and tap it. Place the insert into the installation tool, then hand-tighten it into the tapped hole. Strike the tool to secure the insert and drive the knurls into the surrounding material.
    High-Strength 17-4 PH Stainless Steel—The strongest stainless steel inserts we offer. They handle high-stress installations, such as pump and compressor housings, and the heavy vibration of aircraft parts. They won’t rust in wet and outdoor environments but can’t withstand the harsh chemicals and acids that 316 stainless steel can.
