For a given nut size of nominal diameter, Unified Fine Pitch (UNF) and Unified Coarse Pitch (UNC) represent two different thread densities.  UNC is the most commonly used.  The choice of UNC versus UNF is influenced by the specific application of the job at hand and each type delivers different advantages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUNC \u003c\/strong\u003e- coarse threads are more durable and have greater resistance to stripping and cross-threading. They are also less susceptible to being nicked or damaged and therefore they do not have to be \"handled delicatley\" compared to fine thread (UNF) nuts.  Coarse nuts install much more quickly and are not not affected by plating buildup to the same extent as fine UNF threads on exhaust manifold studs or bolts.\u003cbr\u003e.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUNF\u003c\/strong\u003e - fine threaded bolts are stronger than UNC coarse threaded bolts of the same hardness.  This is due to the fine threaded bolts having a slightly larger tensile stress area.  Fine threads also have less tendency to loosen under vibration due to the fact that they have a smaller helix angle than coarse threads. \u003c\/p\u003e\n\u003cp\u003eUNF also has the advantage of allowing for finer adjustments in applications that require this characteristic.  They can also be more easily tapped into difficult to tap materials and thin walled sections and they require less tightening torque to achieve equivalent preloads to the corresponding UNC nuts\/ bolts.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eManifold Stud Degradation:\u003c\/h4\u003e\n\u003cp\u003eManifold studs are exposed to extreme engine temperatures for prolonged periods of time.  Removing them can be a near impossible task.

For a given nut size of nominal diameter, Unified Fine Pitch (UNF) and Unified Coarse Pitch (UNC) represent two different thread densities.  UNC is the most commonly used.  The choice of UNC versus UNF is influenced by the specific application of the job at hand and each type delivers different advantages.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUNC \u003c\/strong\u003e- coarse threads are more durable and have greater resistance to stripping and cross-threading. They are also less susceptible to being nicked or damaged and therefore they do not have to be \"handled delicatley\" compared to fine thread (UNF) nuts.  Coarse nuts install much more quickly and are not not affected by plating buildup to the same extent as fine UNF threads.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eUNF\u003c\/strong\u003e - fine threaded bolts are stronger than UNC coarse threaded bolts of the same hardness.  This is due to the fine threaded bolts having a slightly larger tensile stress area.  Fine threads also have less tendency to loosen under vibration due to the fact that they have a smaller helix angle than coarse threads. \u003c\/p\u003e\n\u003cp\u003eUNF also has the advantage of allowing for finer adjustments in applications that require this characteristic.  They can also be more easily tapped into difficult to tap materials and thin walled sections and they require less tightening torque to achieve equivalent preloads to the corresponding UNC nuts\/ bolts.\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003ch4\u003eManifold Stud Degradation:\u003c\/h4\u003e\n\u003cp\u003eManifold studs are exposed to extreme engine temperatures for prolonged periods of time.  Removing them can be a near impossible task.

You can use a hand held torch to heat the engine block around the exhaust manifold.  This will expand the stud casing and generate wiggle room.  Note, you will need to let the engine block cool before repeating the process for the next bolt.\u003cbr\u003e\u003cbr\u003e\u003cem\u003e\u003cstrong\u003eStep 5 - Fire and Ice\u003c\/strong\u003e\u003c\/em\u003e\u003cbr\u003eA quicker process involves heating the exhaust manifold bolt itself and then cooling it quickly. You can effect this method by applying a torch directly to the bolt head to heat the stud as rapidly as possible without altering shape.  Next apply an ice cube, (using tongs), directly onto the bolt head.  Then repeat this with a second ice cube.  The rapid loss of heat will result in a contraction\/ change of size and break the rust seal that had formed.\u003c\/p\u003e\n\u003cp\u003eWe have the best price on all m10 exhaust bolts, m10 exhaust studs, and m10 studs.
