The VALUE COLLECTION R98488141 is a fully threaded hex head cap screw designed for general fastening applications across industrial, mechanical, and construction trades. Sized at 5/8-11 thread pitch with a 3-inch length under head, this fastener is manufactured from 18-8 stainless steel with a bright, uncoated finish. The UNC (Unified National Coarse) thread standard provides reliable engagement in a wide range of tapped holes and standard nuts. Installers working in corrosion-prone environments benefit from the inherent rust resistance of 18-8 stainless. Suitable for use wherever a standard hex drive and full thread engagement are required.
This cap screw is used across residential and commercial applications including equipment mounting, structural assemblies, plumbing fixture installation, HVAC component attachment, and general mechanical assemblies. The fully threaded shank allows maximum thread engagement along the entire 3-inch length, making it well suited for through-bolting thin materials or applications that require consistent clamping force from head to tip. Licensed tradespeople and maintenance technicians commonly stock this size for routine service and equipment installation work.
Designed as a standard UNC coarse-thread hex head cap screw suitable for use with 5/8-11 tapped holes, standard hex nuts, and compatible fastener hardware in inch-measurement assemblies.
Install with a properly sized hex wrench or socket driver rated for the fastener size. Verify thread engagement and hole condition before driving to avoid cross-threading. Apply anti-seize compound when installing stainless fasteners into stainless tapped holes to prevent galling. Follow applicable mechanical or structural codes for torque and fastener specifications relevant to the assembly.
