Hex cap screws are manufactured to tighter tolerances as compared to hex bolts. A4 stainless steel is functionally equivalent to 316 grade and is also known as "marine grade". Stainless steel significantly improves resistance to tarnishing or corrosion. The washer face under the head provides a precision bearing surface. The chamfered point improves engagement with a nut or pre-tapped hole.DIMENSIONAL ATTRIBUTES Diameter (Nominal): M5 Thread Pitch: 0.8 Diameter (Dimension): 5mm Length (Nominal): 55mm Thread Length (Nominal): 55mm Across Flats (Basic): 8mm Across Flats (Minimum): 7.78mm Across Flats (Maximum): 8mm Head Height, Overall: 3.5mm Head Height, Overall (Minimum): 3.35mm Head Height, Overall (Maximum): 3.62mmPRODUCT ATTRIBUTES Category: Cap Screws System of Measurement: Metric Brand: Aspen Fasteners Head Style: Hex Head Head Style Detail: Washer Face Drive Style: External Hex Drive Pitch: Coarse Thread Thread Length: Full Thread Thread Direction: Right-Hand Thread Point: Chamfered Point Material: Stainless Steel Material Grade: A4 Stainless Steel Coating: Uncoated Standards and Specifications: DIN 933 / ISO 4017
