Constructed from steel with a black oxide coating, this support features a 3\/8-16 thread and measures 2.5 inches in overall length with a thread length of 1.8125 inches. The pin measures 0.34375 inches in diameter and 0.15625 inches in height. The black oxide finish provides corrosion resistance and reduces light reflection, making it a practical choice for machine shop and assembly environments. Typically installed by machinists, tool and die technicians, and mechanical assembly professionals.\u003c\/p\u003e\u003cp\u003eThis clamp rest support is suited for use in workholding setups where a stable, threaded rest point is required. The 3\/8-16 thread size is a common standard thread pitch widely compatible with modular fixturing systems and clamping hardware. The 0.5625-inch size designation and compact 2.5-inch length make it appropriate for applications where space is limited and precise part positioning is required.

Ensure the mating threaded bore is clean and free of debris before threading in the support. Do not overtighten, as the lead alloy rest element may be damaged by excessive clamping force. Verify workpiece contact point alignment before securing the support in its final position.\u003c\/p\u003e\u003ch4\u003eTechnical Specifications\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Size\u003c\/strong\u003e: 3\/8-16\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOverall Length\u003c\/strong\u003e: 2.5 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThread Length\u003c\/strong\u003e: 1.8125 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSize\u003c\/strong\u003e: 0.5625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Diameter\u003c\/strong\u003e: 0.34375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePin Height\u003c\/strong\u003e: 0.15625 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eNut Height\u003c\/strong\u003e: 0.34375 inches\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMaterial\u003c\/strong\u003e: Steel with Lead Alloy Rest\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFinish\u003c\/strong\u003e: Black Oxide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWeight\u003c\/strong\u003e: 0.7 pounds\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePackage Quantity\u003c\/strong\u003e: 1\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eStandard Information\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBrand\u003c\/strong\u003e: GIBRALTAR\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eManufacturer Part Number\u003c\/strong\u003e: 85548691\u003c\/li\u003e\n\u003c\/ul\u003e","brand":"GIBRALTAR","offers":[{"title":"Default Title","offer_id":51698408128818,"sku":"85548691","price":14.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0270\/4519\/9983\/files\/6b7436bfd4cd6e558d6af4d27606e21e.jpg?v=1788362381","url":"https:\/\/voomisupply.com\/products\/gibraltar-85548691-clamp-rest-support-3-8-16-thread","provider":"Voomi Supply","version":"1.0","type":"link"}
