Three Ways to Fix a Damaged Thread | Insert Tech 101

Being hard in nature, grey cast iron and steel will tend to have exceptional thread strength and thread retention capabilities as long as these materials are protected from corrosion. When thread damage does occur in cast iron and steel, the most common practice is to drill out the existing threads and tap the hole to accept a larger fastener.Three Ways to Fix a Damaged Thread | Insert Tech 101When installed into the larger repair threads, the wire forms a set of threads engineered to meet the original dimension of the stripped-out hole. The repair threads for the HeliCoil insert are made by using a Screw Thread Insert or S.T.I. tap. This is the same type of tap used for some other inserts.The Basics of Thread RollingThread Length vs. Roll Length o Roll work face needs to be calculated for each part to make sure proper clearances are used. o We offer this as a free service to our customers to make sure that the thread roll process and tooling life are optimized. o Rule of thumb = Roll WF = (2.5 x Pitch) + Thread Length CJWinter | www.cjwinter hot rolled screw thread steel re

This will give the tap less hole material to try and cut through. A 1/4-28 is a fine pitch and whole lot easier to tap than a 1/4-20! You won't be able to take much out of the hole with a larger drill.
