Value Collection 701094PR Button Socket Cap Screw 8-36

Product Description

The VALUE COLLECTION 701094PR is a button socket cap screw designed for precision fastening applications where a low-profile head is required. Manufactured from alloy steel with a black oxide coating, this screw measures 1 inch in length under the head and uses a 3/32 inch hex socket drive. It carries a thread size of 8-36 UNF with a Class 3A thread fit and a right-hand thread direction. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it suitable for use in machinery, tooling, fixtures, and equipment assemblies. A hardness rating of 36-43 HRC confirms high tensile strength appropriate for demanding mechanical applications. Licensed tradespeople and assembly technicians are the primary installers of this fastener type.

This button socket cap screw is suited for use in light industrial, mechanical, and precision equipment applications where a smooth, domed head profile is preferred over a standard socket cap head. The 8-36 UNF thread is a fine-pitch designation, making it appropriate for thin-material assemblies or applications requiring fine adjustment and vibration resistance. Typical install scenarios include machine tooling, jigs, fixtures, enclosures, and precision instrument assemblies. Compliance with ANSI/ASME B18.3 and ASTM F835 standards ensures dimensional and mechanical consistency across the fastener.

Key Features

• Button-head profile provides a low, rounded head for flush or near-flush installations
• Alloy steel construction with 36-43 HRC hardness for high-strength fastening
• Black oxide coating offers mild corrosion resistance and a matte appearance
• 3/32 inch hex socket drive for use with standard hex key tools
• Fine-pitch 8-36 UNF thread with Class 3A fit for consistent, close-tolerance engagement
• Meets ANSI/ASME B18.3 and ASTM F835 standards for dimensional and mechanical compliance

Compatibility

Designed as a standard 8-36 UNF button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835, suitable for use wherever a fine-pitch, low-profile alloy steel fastener of this thread size and length is specified.

Installation Notes

Installation requires a 3/32 inch hex key or hex socket bit driver. Confirm mating thread condition and thread class compatibility before installation. Apply appropriate torque using a calibrated torque tool to avoid stripping the hex socket or over-stressing the fastener. Handle black oxide-coated fasteners with clean, dry hands or gloves to preserve the finish and minimize surface oxidation.
