Value Collection 243506 Flat Socket Cap Screw 5/16-18

Product Description

The VALUE COLLECTION 243506 is a flat socket cap screw designed for applications requiring a flush or countersunk fastener profile. The 82-degree flat head seats fully into a countersunk hole, leaving a smooth surface after installation. Driven by a 3/8-inch hex socket, it offers reliable torque transfer without the risk of cam-out common to slotted or Phillips drives. Manufactured from 18-8 stainless steel, this fastener provides solid corrosion resistance in moderately harsh environments. Thread size is 5/16-18 UNC with an overall length of 3/4 inches.

This screw is suited for mechanical assembly, fabrication, and maintenance applications where a countersunk, flush-mount fastener is required. The 18-8 stainless steel construction makes it appropriate for use in environments exposed to moisture, mild chemicals, or outdoor conditions. It is commonly installed by machinists, millwrights, maintenance technicians, and fabricators working with metal plate, brackets, enclosures, and structural assemblies that require a clean, unobstructed surface finish.

Key Features

• 82-degree flat head seats flush in standard countersunk holes for a smooth surface finish
• 3/8-inch hex socket drive provides high torque capacity and reduced cam-out risk
• 18-8 stainless steel construction offers corrosion resistance in wet and outdoor environments
• 5/16-18 UNC thread ensures broad compatibility with standard inch-series tapped holes
• 3/4-inch overall length suits moderate-depth countersunk fastening applications

Compatibility

Designed as a standard inch-series flat socket cap screw for use in any 5/16-18 UNC tapped or through-hole application requiring a countersunk, flush-mount fastener.

Installation Notes

Installation requires a 3/8-inch hex key or socket driver. Ensure the mating hole is properly countersunk to 82 degrees before installation to achieve full head seating. Apply appropriate thread lubricant or anti-seize compound when installing stainless steel fasteners into stainless steel tapped holes to prevent galling. Minimum order quantity for this item is 100 pieces.
