About this item

  • 🚗【Product Specifications】 Weld-on nut features an exact 1/2"-13 thread specification Big OD: 1" (Small OD: .750") length 1.25 inches,With 4 nuts per pack, it can seamlessly connect with standard bolts, meeting the diverse needs of chassis mounting in industries like automotive and machinery.
  • 🚗【Convenient Installation】When the back of the fastener is inaccessible, using this nut allows for quick installation or removal of chassis components. With simple operations, you can create a permanent threaded mounting point. The process is straightforward, and even DIY enthusiasts can master it easily. After welding, the nut fits closely to the flat surface, laying a solid foundation for subsequent installations.
  • 🚗【Durable Structure】The nut is made of sturdy, durable, and easily weldable low-carbon steel through CNC precision machining. The precise threads ensure a reliable connection, preventing loosening and slipping. With excellent welding performance, it stays firmly in place without cracking after welding, providing long-term and stable support for your projects.
  • 🚗【Product Features】The nut adopts a 1.25-inch extended barrel design, achieving deeper thread engagement and making the connection between the nut and the bolt tighter. The extended barrel also optimizes load distribution, enhancing the nut's ability to withstand tensile and compressive forces, and improving its reliability and durability in practical use.
  • 🚗【Wide Applications】In automotive manufacturing, machining, and general manufacturing projects, when sturdy threaded accessories are needed, this nut is an excellent choice. Whether it's fixing components in the engine compartment, installing mechanical transmission devices, or assembling manufacturing equipment, it can play a crucial role with its outstanding performance.

Threaded inserts where needed

Lawrence WardSeptember 2, 2025

Needed to do a custom skid plate on my CJ. Used these to place threaded inserts to match the new modified YJ skid plate. Worked like a champ. Drilled the holes, used a clamp to hold them and a quick zap with the mig and done. Read more

Hits all the marks

TruckinTJuly 9, 2025

Why did you pick this product vs others?: Well machined and tight tolerances. Threads are cut well without burrs. Plenty of meat to weld to and prevent distortion. Solid inserts that just work. Great value! Read more

★★★★★

Drill, weld, and done.

Ausie-FlopDoodleJune 9, 2025

Machining is good, and the part has plenty of meat for easy welding. The threading is clean, and works as expected. I particularly like the length of thread you get, instead of just a few to catch. If you are looking for a solid part that saves some fabrication time and the need to tap your own threads these just might be for you. Seams to be no issue attaching with the MIG welder, buddy is going to do a nice TIG weld to see how clean they weld up. Read more
