M4 x 40mm Hex Set Screw (Fully Threaded Bolt) A2 Stainless Steel DIN 933

M4 hex head set screw 

M4 hex set screw manufactured in A2 stainless steel offering high corrosion resistance making it ideal for internal and external uses. 

Unlike hexagon bolts, which are partially threaded, the hex set screw has a thread extending up to the underside of the head. This fully threaded shank also sees them known as fully threaded bolts in the trade.  

The fully threaded shank makes these screws popular as it ensures they can be used in many situations without running out of thread.  

The hex head also allows for higher torque to be applied with a range of conventional tools making them a versatile choice. 

Engineered for durability and strength and when combined with M4 stainless steel nuts and M4 washers, sees these stainless steel set screws widely used across many industries by DIY enthusiasts and professionals alike.
