Questions
Are HEICO-LOCK washers reusable?
HEICO-LOCK washers can be reused up to 20 times with 10.9 grade bolts. Stainless steel washers should be replaced after single use. Proper orientation must be maintained during reuse.
Do the washers damage equipment surfaces?
Our washers feature unidirectional serrations that create smooth imprints without scoring mating surfaces, minimizing stress risers and equipment damage.
How to verify proper installation without torque devices?
Check for serration imprints on mating surfaces after disassembly. This visual confirmation ensures minimum torque application when measurement tools aren't available.
What quality certifications do you hold?
We maintain ISO 9001 and IATF 16949 certifications. Our production follows DIN 25201-4 standards with statistical process control for zero-defect manufacturing.
Which industries do you serve?
We serve power generation, aerospace, military, automotive, chemical, mining, and medical equipment sectors requiring reliable bolted joint security solutions.
