Value Collection R57001036 Hex Socket Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R57001036 is a hex socket cap screw designed for fastening applications that require corrosion-resistant hardware and a recessed drive. Threaded 1/4-20 UNC, it measures 3.25 inches under the head and accepts a 3/16-inch hex key drive. Constructed from 18-8 stainless steel with a bright, uncoated finish, it delivers solid resistance to rust and oxidation without added surface treatments. This fastener is a standard choice in mechanical assemblies, equipment fabrication, and maintenance applications where a flush or recessed fastener head is required.

This screw is suited for light to medium-duty assemblies in industrial, commercial, and trade environments. The 1/4-20 UNC thread pattern is one of the most common coarse-thread standards in inch-series fastening, making it compatible with a wide range of tapped holes and threaded inserts in metal and engineered plastic components. Typical applications include equipment panels, enclosures, mounting brackets, and structural subassemblies where a hex socket drive is preferred for torque control and clearance.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard tapped holes
• 3.25-inch length under head suits deeper through-hole or tapped fastening applications
• 3/16-inch hex socket drive allows use with standard Allen keys or hex bit drivers
• 18-8 stainless steel construction provides corrosion resistance in moderate environments
• Bright, uncoated finish maintains natural stainless appearance with no added plating

Compatibility

Designed as a standard inch-series hex socket cap screw for use in any application requiring a 1/4-20 UNC thread and a 3.25-inch length under head in stainless steel.

Installation Notes

Install using a 3/16-inch hex key or Allen-style bit driver. Ensure the mating tapped hole or threaded insert is clean and free of debris before installation. Avoid overtightening stainless steel fasteners, as 18-8 stainless is susceptible to galling under excessive torque — use fastener lubricant or anti-seize compound when the application permits. Confirm thread engagement depth meets the requirements of the assembly before final tightening.
