S-93235A783 5/16"-18 x 1" Vented Socket Head Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 18-8 stainless steel construction, ideal for harsh industrial environments and extended service life.
• Superior fastening strength and reliability from a 70,000 psi tensile strength and Rockwell B70 hardness, preventing stripping and failure under high stress.
• Precise and secure thread engagement ensured by the Class 3A thread fit and 5/16"-18 UNC coarse thread profile, reducing the risk of cross-threading.
• Efficient installation and removal with a standard 1/4" hex drive, allowing for high torque application in confined spaces.
• Enhanced performance in pressurized or vacuum applications due to the integrated vent with a 0.078" diameter, preventing pressure buildup.
• Full-length threading for maximum grip and adjustability along the entire 1" length of the screw.
• Compliance with major environmental and safety regulations including RoHS 3 and REACH, ensuring suitability for global industrial supply chains.
