M4X0.7 MARINE GRADE Low Head Allen Socket Cap Screw A4-50 Stainless Steel / DIN 7984
Allen Socket Drive Size: 2.5mm
Low Profile socket head bolts are designed to be used in tight work areas where a reduced head height is required. An allen wrench is used to install these screws, allowing access into spaces where a traditional external hex drive bolt would not fit.
Partially threaded socket cap bolts have an unthreaded length under the head that is stronger than the threaded portion of the bolt. The unthreaded / threaded length dimensions vary by diameter. Fully threaded socket cap screws are meant to engage the entire length with a tapped hole.
Socket head cap screws can be used with many different styles of locking and non-locking nuts, tightly clamping together whatever the cap screw is being used to secure.
Material: A4 / SAE Type 316
A4 / 316 Stainless Steel fasteners are "marine grade" corrosion resistant; suitable for salt water applications. A4 fasteners also offer increased resistance to chemicals when compared with A2 stainless fasteners.
Per DIN EN ISO 3506: A4-50 austenitic stainless steel specifically refers to a tensile strength of at least 500 N/mm2.
Commonly used in wet environments. Popular across a wide range of industries: automotive, agriculture, photographic, medical / surgical, food processing, clean energy, etc.
Also known as:
Low head or thin head socket cap screw or hexagon socket head cap screw. Reduced height cylindrical head screw meant to be used with an allen wrench.
