The heads of grade 5 steel fasteners are typically marked with 3 raised radial lines. The washer face under the head provides a precision bearing surface. Grade 5 steel fasteners have a minimum tensile strength of 105,000 pounds per square inch. The chamfered point improves engagement with a nut or pre-tapped hole. In general, fine thread fasteners are about 10% stronger than coarse threads under static loading.DIMENSIONAL ATTRIBUTES Diameter (Nominal): 1\/4' Thread Pitch: 28 Diameter (Dimension): 0.25' Diameter (Minimum): 0.245' Diameter (Maximum): 0.250' Length (Nominal): 3\/8' Thread Length (Nominal): 0.375' Across Flats (Basic): 7\/16' Across Flats (Minimum): 0.428' Across Flats (Maximum): 0.438' Head Height, Overall: 0.1563' Head Height, Overall (Minimum): 0.150' Head Height, Overall (Maximum): 0.163'PRODUCT ATTRIBUTES Category: Cap Screws System of Measurement: Inch Brand: Aspen Fasteners Head Style: Hex Head Head Style Detail: Washer Face Head Markings: Three radial lines 120 degrees apart and manufacturer ID Drive Style: External Hex Drive Pitch: UNF Fine Thread Thread Direction: Right-Hand Thread Point: Chamfered Point Material: Steel Material Grade: Grade 5 Coating: Zinc Plated Coating Color: Clear Origin: Made in U.S.A.
