💡 What is the correct clearance hole size for installing 1 4 inch coiled spring pins in auto repair
A properly sized hole keeps these fasteners handy because the coiled design locks down super tight without extra hardware.
- Aim for a nominal 0.256 inch clearance to seat the pin flush every time
- Deburr the edges thoroughly so the spring coils slide in smooth during assembly
- Check material thickness to confirm it supports the full 7800 pound shear load
- Swab excess oil from mating surfaces so static friction holds plates steady under load
