S-97248A321 M8 x 30 mm DIN 603, ISO 8678 Carriage Bolts

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction, ideal for harsh or outdoor environments
• Exceptional anti-rotation performance due to the integrated square neck that locks securely into materials
• High tensile strength of 70,000 psi ensures reliable load-bearing capacity for demanding applications
• Wide, rounded carriage head provides a larger bearing surface and a finished appearance while resisting pull-through
• Coarse M8 x 1.25mm thread enables faster installation and reduced risk of cross-threading
• Fully threaded design offers maximum engagement and clamping force along the entire 30mm length
• Compliance with DIN 603/ISO 8678 standards guarantees dimensional accuracy and interchangeability

Professional Applications & Engineering Value

This M8 carriage bolt is engineered from 18-8 stainless steel to solve critical challenges in industrial assembly. Its excellent corrosion resistance makes it a prime choice for applications exposed to moisture, chemicals, or weathering, such as in construction, agricultural machinery, and marine equipment. The square neck is a key feature that bites into the mounting material, preventing the bolt from spinning during nut tightening—this is invaluable in wood-to-metal or composite material fastening where a secure, non-rotating fit is essential. The fully threaded body and Class 8g thread fit ensure consistent clamping force and reliable performance in heavy-duty structural connections, from trailer beds to industrial framing.

Specification Summary & Compliance

This bolt features a metric thread with an M8 diameter, 1.25mm pitch, and a Class 8g thread fit for standard industrial tolerances. It is manufactured to meet the dimensional requirements of DIN 603 and ISO 8678 standards. The product is RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring it is free of hazardous substances and safe for use in regulated markets.
