✔️ 1/4-20 coarse thread zinc coated steel blind inserts

This 15 piece short jack nuts kit delivers a foolproof mounting method for thin sheet metal, plastic trim, and fiberglass doors.

✅ Matches common 1/4-20 coarse thread machine screw standards
✅ Flaring leg design clamps securely without stressing thin walls

💡 What is a blind threaded insert used for securing fragile panel surfaces? These jack nuts deliver a dependable anchor point for thin automotive bodywork and plastic housings, making them a handy addition to any workshop drawer: - Push the zinc plated unit into your pre measured hole before contacting the wrench - Rotate the friction handle until the steel shaft collapses and grips the inner walls - The formed barrel accepts standard hex bolts repeatedly without cross threading or loosening - This hands on method cuts downtime on shop repairs by skipping messy weld nuts or epoxy setups
