Value Collection 3tscs94f012 Hex Socket Cap Screw 1/4-28 Unf

Product Description

The VALUE COLLECTION 3tscs94f012 is a hex socket cap screw designed for applications requiring a secure, flush-clearance fastener with an internal drive. Threaded to the 1/4-28 UNF fine-pitch standard, it features a 3/16-inch hex drive and a 3/4-inch length under head. The fastener is manufactured from Grade 316 stainless steel with a bright, uncoated finish, making it well suited for environments where corrosion resistance is a priority. Machinists, millwrights, HVAC technicians, and plumbing tradespeople commonly use socket cap screws when access space limits the use of external-drive fasteners.

This screw is appropriate for light structural, equipment-mounting, and panel-fastening tasks across a wide range of trade applications. The fine 1/4-28 UNF thread pitch provides greater thread engagement per inch compared to coarse-pitch equivalents, which supports use in thinner materials and vibration-prone assemblies. Grade 316 stainless steel offers enhanced resistance to chlorides and harsh process environments relative to Grade 304, making this fastener a practical choice for marine, food service, chemical, and outdoor mechanical installations.

Key Features

• 1/4-28 UNF fine-thread form for increased engagement in thin stock and vibration-sensitive applications
• 3/16-inch internal hex drive accepts standard Allen or hex key tooling
• 3/4-inch length under head suits moderate-depth through-hole and tapped-hole installations
• Grade 316 stainless steel construction for superior corrosion resistance in harsh or wet environments
• Bright, uncoated finish — no coating thickness to account for in precision-fit assemblies

Compatibility

Designed as a standard replacement or stock fastener for any assembly requiring a 1/4-28 UNF hex socket cap screw with a 3/4-inch length under head and a 3/16-inch drive.

Installation Notes

Install using a 3/16-inch hex key or Allen driver; ensure the driver is fully seated in the socket before applying torque to avoid cam-out and socket damage. Verify that the receiving tapped hole or nut is also 1/4-28 UNF to prevent cross-threading. When fastening into stainless steel tapped holes, apply an appropriate anti-galling compound to reduce the risk of thread seizure. Follow applicable mechanical and structural codes for the specific application and jurisdiction.
