About This Product

BUMAX is a high-strength stainless steel bolt developed for the purpose of design improvement (downsizing and weight reduction). We use Swedish austenitic steel SUS316L material, without heat treatment, and through heading and rolling during the bolt manufacturing process, we have ensured a strength of 8.8 and 10.9, equivalent to that of steel bolts.

■High strength: 4 times the proof strength of SUS304 (A2-50) and 2 times that of SUS316 (A4-70)

Although it is made of stainless steel, BUMAX satisfies the same strength class 10.9 as steel bolts, and is four times stronger and twice as strong (yield strength ). BUMAX has been able to downsize the 20mm diameter bolt design of SUS304 (A2-50) to 10mm diameter, achieving a weight reduction of one-fourth.

■Corrosion resistance: No corrosion occurred even after 10 years of testing in marine environment.

BUMAX has obtained better results than SUS after 10 years of atmospheric exposure in coastal areas, and has proven three times more corrosion resistant than SUS316 in a 20% sulfuric acid corrosion test. Guaranteed 30 years of corrosion resistance even when used on ships exposed to the sea. We guarantee overwhelming corrosion resistance that surpasses other stainless steel bolts.

■Features of locking nut BUMAX Lock 88

- All-metal lock nut. - Locking nut specifically for stainless steel bolts. ・Free spinning. (Can be tightened without resistance) - Equipped with a special thread shape designed to lock when tightened. ・Please use standard screws (6g) for the male screws. ・When tightened, the load is distributed almost equally to all the screws mating with the male screw. As a result, a greater frictional holding force is generated, which prevents loosening from occurring. ・When tightening the BUMAX lock, it is important to apply a high tightening torque. Demonstrates strong locking properties when high torque is applied. ・Can be used repeatedly over 10 times.

■Specifications

・Product standards: ISO-4032, JIS B1181 ・Material: A4-SS 2343 316L HiMo ・Thread standards: ISO 261/262, JIS B0205/B0209, ISO 4161 (flange), DIN 6923 (flange) ・Thread accuracy: 6H ・Guaranteed load: 800N/mm2
