Should I use anti seize on head bolts?

There is one time you should always use anti-seize when torquing cylinder head bolts: when it’s a diesel engine. As a rule, you need to chase both the male and female threads and use anti-seize on diesel engines.

Should I put anything on head bolts?

So anything that reduces thread friction also reduces the amount of torque that’s required on the fastener. Or put another way, anything that reduces friction also multiplies the clamping load exerted by the head bolt at a given torque reading.

Where should you not use anti-seize?

Do not use anti-seize as a lubricant such as on caliper slide pins or on threads for a bushing press or any mechanical assembly that requires a lubricant. Do not use anti-seize on exposed threads because the compound can attract contaminants that may contribute to thread damage when the fastener is removed.

Should you lube head bolts before torquing?

you should always lube anything that is going to be torqued or else you won’t get an accurate reading…you want to be measuring the torque without any friction interfering with the reading.

Why would you use anti-seize on a bolt?

Anti-seize products are applied to bolts, fasteners, flanges and other clamped interfaces to prevent galling, seizing and corrosion, as well as lubricating to ease disassembly.

What kind of sealant do you use on head bolts?

Loctite Headbolt & Water Jacket Sealant is a single-component anaerobic hybrid that lubricates fasteners during assembly, as well as seals the gaps between the threads.

When should you use anti seize?

Anti-seize should be used when two metals are involved (similar or dissimilar), when threads may be exposed to corrosion and fastener that frequently get removed.

When should I use anti seize grease?

Prevents galling. Protects against rust and corrosion.


Grease Anti-Seize
Good for fast-moving, low contact, low pressure applications Good for slow-moving, extremely high contact and high-pressure applications
Typically not suitable for temperatures above 400°F Suitable for high temperature environments

Does anti seize affect torque?

The torque applied to a fastener with an antiseize compound pre- applied to the threads will ensure uniformity through out the process but will increase the Clamp Load compared to an unlubricated bolt. … Torque values may also have to be reduced when the fastener is threaded into aluminum or brass.

Do you use lube on head bolts?

Motor oil will be fine. It’s cheap, plentiful and what Honda recommends using. Head bolts are usually torque to yield and usually require replacement after use.

Should you lubricate bolts?

By lubricating the fastener the results are further improved and scatter is reduced to 10%-15% which is about as good as can be achieved using torque control methods. When tightening a fastener ALWAYS use a controlled method. Unless specifically told not to, always lubricate the fastener.

Can you put oil on bolts?

Anything foreign, like oil, dirt, dust, etc., in the bolt hole may cause the bolt to bottom out prematurely and, as stated above, throw off torque readings. Even with head studs, you are not supposed to apply oil on the side that goes into the block. Keep it clean and dry!

How long does Anti Seize last?

Anti-Seize Special™ has a shelf life of 5 year or more when stored in a closed container. Shelf life may be much longer depending upon storage location and conditions. Store with container tightly sealed in a cool dry place for optimum shelf life.

Does anti seize seal threads?

Anti-seize materials protect threaded and slip-fitted metal parts from rust, corrosion, galling and seizing at high temperatures. … Specific formulations cater for the type of metal used for the threads, as well as temperature extremes.

Can I use grease instead of anti seize?

You can use grease quite effectively as an anti-seize compound. It’s not as good in high temperature applications, but there aren’t any of those on a bike. However, NEVER use anti-seize compound as a lubricant.
