10pcs M16-2.0x540mm A4 Stainless Hex Bolts for Marine/Construction

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): M16 Thread Pitch: 2.0 Diameter (Dimension): 16mm Length (Nominal): 540mm Thread Length (Nominal): 57mm Across Flats (Basic): 24mm Across Flats (Minimum): 23.67mm Across Flats (Maximum): 24mm Head Height, Overall: 10mm Head Height, Overall (Minimum): 9.82mm Head Height, Overall (Maximum): 10.18mm Body Diameter (Minimum): 15.73mm Body Diameter (Maximum): 16mmPRODUCT 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: Part Thread Thread Direction: Right-Hand Thread Point: Chamfered Point Material: Stainless Steel Material Grade: A4 Stainless Steel Coating: Uncoated Standards and Specifications: DIN 931 / ISO 4014
