#10-24 x 1/2" Tamper-Resistant Cap Screws, Torx® Equivalent 6-Lobe with Solid Post, Undercut Flat Head, Driver Size: 20TXH, 18-8 Stainless Steel

Torx® Tamper-Resistant Cap Screws manufactured from 18-8 stainless steel, incorporate a solid post formed in the center of the recess during the heading process.
