Detailed product description

Product Introduction

Loctite 277 is designed for permanent locking and sealing of threaded fasteners. The product cures when there is no air between enclosed metal surfaces and prevents loosening and leaking due to shock and vibration. Typical applications include locking and sealing of large bolts and studs (M25 or larger).

Common questions

Before you send the enquiry

Yes. Tell us the grade and how you intend to use it, and we will send the manufacturer’s current technical data sheet. We pass manufacturer documentation through unchanged rather than reissuing it under our own name.

No — and you should be careful with anyone in our position who says they do. What we supply is the document chain: which document exists, who issued it, what it covers, and notification when it changes. Compliance statements come from the manufacturer, not from us.

That is one of the most common reasons engineers contact us. Equivalence is a ladder, not a yes/no answer — some claims are backed by a matching data sheet, others only by chemistry family. We will tell you which rung a given substitution sits on before you commit to it.

Packaging sizes shown on this page are the standard units for this grade. Sample quantities for evaluation are handled case by case — tell us the trial you are planning and we will scope it with you.

Tell us what you are bonding

Substrates, process window, and the failure you are trying to design out. An engineer answers, not a form.

We do not issue compliance certificates. We supply the material, the manufacturer’s documentation, and the engineering judgement in between.
