Value Collection 701089PR Button Socket Cap Screw 8-36

Product Description

The VALUE COLLECTION 701089PR is a button socket cap screw designed for applications where a low-profile head and high clamping strength are both required. Sized at 8-36 x 1/2 inch, it features a 3/32 inch hex socket drive and is fully threaded along its 1/2 inch length under the head. Manufactured from alloy steel with a black oxide coating, it achieves a hardness rating of 36-43 HRC. Conforming to ANSI/ASME B18.3 and ASTM F835, this fastener is a standard choice for mechanical assemblies where head clearance is limited. Licensed fastener installers, machinists, and maintenance technicians install this screw in precision and structural applications alike.

This screw is suited for residential and commercial mechanical assemblies, machine frames, brackets, panels, and enclosures where a flush or near-flush head profile is needed. The black oxide finish provides mild corrosion resistance and reduces light reflection, making it appropriate for tooling fixtures, equipment enclosures, and general industrial hardware. The 8-36 UNF thread pitch offers finer thread engagement than coarse-thread equivalents, which is useful in thin-material and higher-vibration installations. Sold individually with a minimum order quantity of 100 pieces per order.

Key Features

• Button head profile provides low clearance height of 0.087 inches for tight-space installations
• 3/32 inch hex socket drive for standard hex key or bit-driver installation
• Fully threaded 8-36 UNF right-hand thread with 3A fit class for precise engagement
• Alloy steel construction with 36-43 HRC hardness for reliable clamping load
• Black oxide coating for mild corrosion resistance and low-reflectance finish
• Meets ANSI/ASME B18.3 and ASTM F835 fastener standards

Compatibility

Designed as an OEM-style or replacement fastener for any application requiring an 8-36 UNF button socket cap screw conforming to ANSI/ASME B18.3 and ASTM F835 standards.

Installation Notes

Install using a 3/32 inch hex key or matching hex bit driver. Verify mating thread is 8-36 UNF before installation to avoid cross-threading. Power down or de-energize any equipment before removing or replacing fasteners on live assemblies. Do not substitute a coarse-thread driver or mismatched hex key, as these can strip the socket recess.
