The M8 hexagon bolt typically requires a 13mm spanner or socket.
A2-304 stainless steel offers good corrosion resistance, but it is generally recommended to use A4-316 grade stainless steel for direct, high-salinity marine environments.
No, this product is supplied as a box of 100 bolts only; nuts and washers must be purchased separately.
As they meet DIN 931 standards, these bolts feature a partial thread rather than a full thread.
Each box contains 100 individual bolts.
Stainless steel can gall; ensure the threads are clean and consider using an anti-seize lubricant to facilitate smoother installation.
Ensure the spanner or socket fits perfectly and is fully seated on the bolt head before applying torque.
Verify that your nut is also M8 metric. Ensure the bolt thread is not damaged or obstructed by debris.
For installation, ensure you are using an appropriately sized metric spanner or socket. Since these are M8 bolts, an 13mm tool is typically required. While A2-304 stainless steel is highly resistant to elements, avoid using these bolts in environments with high chloride concentrations, such as swimming pool areas or immediate proximity to saltwater, as this can cause pitting. Store in the original packaging to keep the threads clean and protected from damage until needed. If the bolts are being installed into a metal substrate, it is recommended to apply a small amount of anti-seize lubricant to the threads to prevent galling, a common issue with stainless steel fasteners.
