Value Collection R57001040 Hex Socket Cap Screw 1/4-28

Product Description

The VALUE COLLECTION R57001040 is a hex socket cap screw designed for secure fastening in applications requiring fine-thread engagement and corrosion resistance. This screw features a 1/4-28 UNF thread specification, a 3-1/2 inch length under head, and a 3/16 inch hex drive. It is manufactured from 18-8 stainless steel with a bright, uncoated finish. Mechanics, millwrights, and maintenance technicians commonly install this fastener in precision assemblies where a fine thread pitch provides tighter clamping force and resistance to vibration loosening.

This fastener is suited for use in light industrial, mechanical, and maintenance applications where stainless steel construction is required to resist corrosion. The 1/4-28 UNF fine thread makes it appropriate for assemblies with thinner materials or where precise torque control is needed. It is sold in a minimum order quantity of 5 pieces and is compatible with standard 3/16 inch hex keys and hex-drive sockets.

Key Features

• 1/4-28 UNF fine thread for tight clamping and vibration resistance
• 3-1/2 inch length under head for deeper engagement in thick assemblies
• 3/16 inch hex socket drive compatible with standard hex keys and bit sets
• 18-8 stainless steel construction provides corrosion and oxidation resistance
• Bright, uncoated finish with no added plating that could affect thread tolerance

Compatibility

Designed as an OEM-style replacement or standard fastener for mechanical assemblies requiring a 1/4-28 UNF hex socket cap screw with a 3-1/2 inch length under head.

Installation Notes

Installation requires a 3/16 inch hex key or hex-drive bit rated for the fastener size. Always ensure the mating thread is clean and free of debris before installation. De-energize or lock out any equipment before replacing fasteners on live assemblies. Follow applicable industry torque specifications for 1/4-28 stainless steel fasteners per the relevant mechanical or equipment service documentation.
